Question

Write Lewis dot symbols for the following atoms of flowering elements:
1Mg
2Na
3B
4O
5N
6Br​

Answer 1

Explanation:

Mg: There are two valence electrons in Mg atom. Hence, the Lewis dot symbol for Mg is:

<br> Na: There is only one valence electron in an atom of sodium. Hence, the Lewis dot structure is:

<br> B: There are 3 valence electrons in Boron atom. Hence, the Lewis dot structure is:

<br> O: There are six valence electrons in an atom of oxygen. Hence, the Lewis dot structure is:

<br> N: There are five valence electrons in an atom of nitrogen. Hence, the Lewis dot structure is:

<br> Br: There are seven valence electrons in bromine. Hence, the Lewis dot structure is:
