Question

3. How many valence electrons are in each element below? What is the Atomic number of each element? F Electrons: Atomic #: CI Electrons: Atomic #: Br Electrons: Atomic #: Electrons: Atomic #:​

Answer 1

Here are the number of valence electrons and the atomic number for each element you've mentioned:

1. F (Fluorine)

- Valence Electrons: 7

- Atomic Number: 9

2. Cl (Chlorine)

- Valence Electrons: 7

- Atomic Number: 17

3. Br (Bromine)

- Valence Electrons: 7

- Atomic Number: 35

4. I (Iodine)

- Valence Electrons: 7

- Atomic Number: 53

All these elements are from Group 17 of the periodic table, also known as the halogens, and they all have 7 valence electrons. The atomic number represents the number of protons in the nucleus of the atom and is unique for each element.
