Any help with any of these would be greatly appreciated!

1.) What is the correct electronic configuration for Mo? 
 
b [Kr]4d55s1
c [Ar]3d54s1

2.) How many orbitals are allowed in a subshell if the angular momentum quantum number for electrons in that subshell is 3? 

b 3
c 7
   
7.) What is the primary determiner of an atom's chemistry? 

a valence electrons
b nuclear charge
c size of the nucleus

Please show your attempts.

1.) What is the correct electronic configuration for Mo? 
 
b [Kr]4d55s1
c [Ar]3d54s1

See periodic table

2.) How many orbitals are allowed in a subshell if the angular momentum quantum number for electrons in that subshell is 3? 

What does the highlighted information tell you about the subshell in terms of s, p,d, f...etc.

7.) What is the primary determiner of an atom's chemistry? 

a valence electrons
b nuclear charge
c size of the nucleus

Consider Na and K. They have similar chemistry, why?
