The elements in group 17 are known by the name halogens. They are non-metal elements and are at times referred to as salts.
Non-metals in general are poor conductors of electricity. The elements generally regarded as nonmetals are: hydrogen (H) In Group 14: carbon (C) In Group 15: nitrogen (N), phosphorus (P) Several elements in Group 16, the chalcogens: oxygen (O), sulfur (S), selenium (Se) All elements in Group 17 - the halogens All elements in Group 18 - the noble gases
All elements in a group have same chemical properties. They have same number of valence electrons.
Atomic mass
Krypton is a part of the family of elements known as the noble gases. They all lack odor and color, and they are barely reactive.
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
Caucus. Also, caucus is the name given to either a group of all Democrats or a group of all Republicans.
a group
There are three sets of ions where the charges are given correctly: Group 1 elements (e.g., Na+), Group 2 elements (e.g., Mg2+), and aluminum (Al3+). These ions have fixed charges that do not vary.

Of what group??
Group 1 elements have an oxidation number of +1.
All elements in a group have same chemical properties. They have same number of valence electrons.
All elements in the groups (excluding transition metals) have the same number of electrons as the group number.
All elements in the same A group will have the same number of valence electrons.
Atomic mass
Same elements of group have same valency. They possess same chemical behaviour.
