Which is the correct lewis dot diagram for nitrogen?

c

Explanation:

The five dot represent the five valence electrons of nitrogen.

Valence electrons are the electrons that form chemical bonds with other elements. The number of valence electrons of Nitrogen is gotten by looking at the group nitrogen belongs to, Nitrogen belongs to group 5

Next create a square around nitrogen, then place one of the valence electron on each side of the square, the last electron is placed beside any of the other electrons.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
