fluorine atomic number 9
neon atomic number 10
Silicon atomic number 14 Phosphorus atomic number 15
sulphur atomic 16
Germany atomic number 32
tin atomic number 50


1 Identify the element that has highest atomic radius
2 identify the period number of oxygen
3 identify the group number of neon
4 if the molecular formula of nitrogen trioxide is N2O3 . what is the molecular formula of oxide of phosphorus ​

Answer 1

Answer:

Explanation:

1. Tin, since it has highest atomic number, which means that it is placed comparatively down (atomic radii increases as we go down)

2. oxygen is in period 2, because it has 2 shells( no of shells= period number)

3. neon is in group 18 or group 0 since it is a noble gas

4. P₂O₅
