Yes, Be2-1 exists in the gas phase.
yes
Yes, it will exist in the gas phase.
Halogens are considered to be diatomic molecules. They exist in gas (F2, Cl2), liquid (Br2) and solid phase (Iodine I2).
Solid, liquid or gas - it depends on the non-metal.
This is the a change of phase from liquid to gas.
All elements have a gas phase.
Yes, you can.
Yes, Be2-1 exists in the gas phase.
Yes, it will exist in the gas phase.
One would most likely see metal ions in solution with liquid water.
Yes
This change of phase doesn't exist; probable you think to a chemical reaction in gaseous phase.
Substance at Vapour - Liquid phase equilibrium can exist as both liquid or gas at the same time.
At the boiling point a change of phase exist: from liquid to gas.
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
Beryllium has 4 electrons and is not isoelectronic with any noble gas. However Be2+ is isoelectronnic with helium.
Indium can be solid, liquid or gas. At room temperature, indium is a solid.
