Halogens F (fluorine), Cl (chlorine), Br (bromine), I (iodine), At (astatine)
What elements would form anions most easily?
Halogens are very reactive: F, Cl, Br, I.
How many nonmetals are in group 17 on periodic table?
There are five nonmetals in Group 17, also known as the halogens, on the periodic table. They are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).

Which mineral is a halogen?
Halogens are: F, Cl, Br, I, At, Uus.
How does Na Br2--NaBr balance?
Na + Br ₂→ NaBr This happens because: When certain diatomic elements (Br, I, N, Cl, H, O, F) are alone you add a 2 as a subscript so they are (Br₂, I,₂ N₂, Cl₂, H₂, O₂, F₂). But when you cross Na (which has a charge of +1) with Br (which has a charge of -1) They cancel and you get NaBr. Na + Br ₂→ NaBr This happens because: When certain diatomic elements (Br, I, N, Cl, H, O, F) are alone you add a 2 as a subscript so they are (Br₂, I,₂ N₂, Cl₂, H₂, O₂, F₂). But when you cross Na (which has a charge of +1) with Br (which has a charge of -1) They cancel and you get NaBr.

What element as the same number of protons as the sum of the two elements directly above it?
Phosphorous (P) has Nitrogen (N) and Oxygen (O) above it. P=15 N=7 O=8 P=O+N Chlorine (Cl) had Oxygen (O) and Fluorine (F) above it. Cl=17 O=8 F=9 Cl=O+F Bromine (Br) has Chlorine (Cl) and Argon (Ar) above it. Br=35 Cl=17 Ar=18 Br=Cl+Ar
What element is found in group 17 of the periodic table?

What can actinium combine with?
Actinium react with halogens (F, Cl, Br, I), oxygen, sulphur, etc.
Electronegativity changes as you descended a group?
it decreases (check for instance the halogenes - F, Cl, Br, I, At)
