Using the periodic table entry below, match the phrases with their corresponding values. Mo
Molybdenum

1. atomic number
1
2. atomic mass
18
3. number of valence electrons
54
4. number of electrons in the n = 3 shell
96
5. number of neutrons
42

Explanation:

Molybdenum is a chemical element. It is denoted by Mo. In this problem, we need to match the phrases with their corresponding values using periodic table.

Atomic no = 42

Atomic mass = 95.94 amu or 96

No of valance electrons = The elctronic configration of Molybdenum is                                       [Kr] 4d⁵ 5s¹. It means there is 1 valance electron in it.

No of electrons in the n = 3 shell = 18

No of neutrons = 54
