The group that doesn't combine is the Noble Gasses. They have full valence shells, so they don't need to bond with other atoms.
Yes.
Gallium is in group 13 of the periodic table. The other elements in this group are Boron, Aluminum, Indium, and Thallium.
Those gases are called noble gases. They are i the 18th group of the periodic table.
Elements from the group 2 of the periodic table form cations.
The Group 0 - Inert Gases group are all (exc. Radon) highly unreactive, and so don't chemcially combine with other elements.
Oh, dude, beryllium can combine with oxygen, carbon, and other elements to form compounds. It's like a social butterfly of the periodic table, always mingling and making new friends. So, yeah, beryllium can totally bond with a bunch of different elements, if it feels like it.
A group of elements that rarely combine with other elements because they already have eight electrons in the outer shells is a Noble Gas
Metals form salts.
They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
No, iodine is not a noble gas. Iodine belongs to the halogen group in the periodic table, which contains elements that are highly reactive. Noble gases are a separate group of elements that are inert and do not readily combine with other elements.
Noble gases, such as helium and neon, are the group of elements that do not combine easily with other elements because they have a full outer electron shell, making them stable and less likely to form chemical bonds.
They were once labeled group 0 in the periodic table because it was believed they had a valency of zero, meaning their atoms cannot combine with those of other elements to form compounds.
