Alkali Metals
Group 1 Metals
Noble gases (or group 18 elements)
The elements in group 17 are known by the name halogens. They are non-metal elements and are at times referred to as salts.
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Group 16 of the periodic table of the elements (chalcogens elements)
Group IA or group 1 elements are known as alkali metals.
The general name given to the elements of Group IA (1) is alkali metals.
Group 1 Metals
base in my experience.... because of the gravity of the earth...
Both Group IA and IIA elements have low ionization energies because they have one or two valence electrons that are easily removed. Group IA elements have a lower ionization energy compared to Group IIA elements due to the increased distance from the nucleus and increased shielding effect in Group IA.
Another name for Group 17 (VIIA) Elements is Halogens.
The most electrons an outer shell for group IA metals can have is 2 because IA metals are of the s energy level the max they can hold in an orbital is 2 electrons.
In the old numbering system, "A" simply refered to the the left side of the table. Group IA,IA are alkali metals.
Chromium Group
Noble gases (or group 18 elements)
They're called the alkali metals, and are comprised of lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and Francium (Fr). Group 1A also includes hydrogen (H), though that isn't an alkali metal.
