Question

Lewis dot structures are models used to show what type of subatomic particle of an

atom?

Answer 1

Answer: Lewis dot structures are models used to valence electrons.

Step-by-step explanation:

Lewis dot structures are the structures which represent the valence electrons of the element around the chemical symbol of the element.

For example : Flourine is an element which belong to group 17 and is a halogen. Atomic number of fluorine is 9 that means it contains 9 electrons, Thus the electronic configuration is represented as:

`1s^22s^22p^5`

Thus the valence electrons are 7. Thus 7 electrons are represented around chemical symbol of Flourine i.e. F
