Chlorine by itself is not acidic nor basic because it contains no H+ ions, but when it reacts with water forming hydrochloric and hypochlorous acids it becomes an acid solution.
Under standard conditions iodine is a dark blue-black solid. As a gas, iodine is a purple vapor. Iodine is a fairly active element, but is somewhat less active than the other halogens above it in the periodic table which include bromine, chlorine, and fluorine. Iodine can form compounds with many elements.
All of these chemicals produce salt with similar properties and the most common is sodium chloride (NaCl) or common table salt. In a salt system the salt water is used to produce chlorine through a process called electrolysis.
Has vacant 3d orbitals. So when the chlorine atom or molecule comes in contact with sunlight it's electrons get transferred to vacant 3d orbitals. At room temperature in sunlight the electron aquires energy of only green light.
Chlorine is a clear amber-colored liquid about 1.5 times heavier than water. Gaseous chlorine is greenish-yellow, about 2.5 times as heavier than air.
An oil is any nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (does not mix with water, literally "water fearing") and lipophilic (mixes with other oils, literally "fat loving").
Chlorine gas can be recognized by its pungent, irritating odor, which is like the odor of bleach. Chlorine gas appears to be yellow-green in color. Chlorine itself is not flammable, but it can react explosively or form explosive compounds with other chemicals such as turpentine and ammonia.
As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor.
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Potassium is classified as an "Alkali Metal" and located in Group 1 elements of the Periodic Table.
The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.
Magnesium Is Safe and Widely Available. Magnesium is absolutely essential for good health. The recommended daily intake is 400–420 mg per day for men and 310–320 mg per day for women (48). You can get it from both food and supplements.
Answer and Explanation: Lithium (Li) is an element that is a solid at room temperature. It is an alkali metal as listed on the periodic table of elements. It is silvery-white
At room temperature, and as another answer says, at STP, it is a solid. But if you heat it enough, it can change states. At under 650 degrees Celsius, it's solid. At over 1107 degrees Celsius, it's gaseous.
Magnesium oxide, MgO, is an ionic solid. It has a high melting point of 2800°C.

Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). Because of its stability, MgO is used as a model system for investigating vibrational properties of crystals.
Transition metals are superior conductors of heat as well as electricity. They are malleable, which means they can be shaped into sheets, and ductile, which means they can be shaped into wires. They have high melting and boiling points, and all are solids at room temperature, except for mercury (Hg), which is a liquid.
Gold is a chemical
element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a
pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.

The halogens exist, at room temperature, in all three states of matter: Solid- Iodine, Astatine. Liquid- Bromine. Gas- Fluorine, Chlorine.
Liquids around room temperature. The only liquid elements at standard temperature and pressure are bromine (Br) and mercury (Hg). Although, elements caesium (Cs), rubidium (Rb), Francium (Fr) and Gallium (Ga) become liquid at or just above room temperature.
Only two elements are liquid at standard conditions for temperature and pressure: mercury and bromine. Four more elements have melting points slightly above room temperature: francium, caesium, gallium and rubidium.
Most chemical elements are solid at room temperature. Some elements exist as gases but only two elements, mercury (Hg) and bromine (Br) are liquids at room temperature (approx 25ºC). Liquids around room temperature.
At standard temperature and pressure, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2. Since hydrogen readily forms covalent compounds with most nonmetallic elements, most of the hydrogen on Earth exists in molecular forms such as water
Phosphorus (P), nonmetallic chemical element of the nitrogen family (Group 15 [Va] of the periodic table) that at room temperature is a colourless, semitransparent, soft, waxy solid that glows in the dark.
As humans, we're not built to ingest solid oxygen. To be solid, it must be frozen to −361.82 °F (ouch!) and our stomachs, even if they could tolerate frozen oxygen pellets, are unable to work like lungs to efficiently move oxygen into our circulatory system.
Solid oxygen O2, like liquid oxygen, is a clear substance with a light sky-blue color caused by absorption in the red part of the visible light spectrum.
Oxygen is a basic sub-atomic structure, where singular oxygen molecules are attached to each other by solid covalent bonds. Subsequently, a low measure of energy is required to beat these feeble forces and oxygen has a low breaking point. In this way, at room temperature, oxygen is a gas.
No, you can't squeeze air hard enough for it to become a solid. At least, not at room temperature. At 65K air is a liquid and at 165 it is a gas, but squeezing it hard enough will eventually produce a solid within that temperature range.
oxygen is an extremely powerful oxidizer. Eating its solid form at temperature of −218 °C will obviously freeze you to death. And swallowing an excessive amount of oxygen into your throat makes the flammable fat in your throat react with the oxygen immediately. And burn up.
Matter can be solid, liquid or gas.
These three main forms of matter all have weight and take up space. A desk, pencil, computer and toy truck are solid. Water and milk are liquids.Yes, air is matter because it is a gas composed mostly of nitrogen, oxygen, and argon, and gases do have mass because they're molecules bouncing around a contained volume (here, the atmosphere).
Liquid oxygen has a density of 1.141 g/cm3 (1.141 kg/L or 1141 kg/m3), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 101.325 kPa (760 mmHg).
The squished hydrogen is a precursor to a state of matter first proposed in the 1930s, called atomic solid metallic hydrogen. When cooled to low enough temperatures, hydrogen (which on Earth is usually found as a gas) can become a solid; at high enough pressures, when the element solidifies, it turns into a metal.
