Question

For the following elements, use the periodic chart and draw the Bohr model, state how many electrons ,protons,neutrons are present, state if the atom is reactive or non-reactive, and how many valence electrons there are.

1.Nitrogen (N)

2.Neon (Ne)

3.Potassium (K)

Answer 1

Hints:

Theoretically the valence number of the nitrogen would be 3, however in the table appear others, although the atom is only unstable this element appears as a diatomic molecule so when being with another atom of nitrogen stabilizes

Theoretically the valence number of the nitrogen would be 6 but is 0, as it is a noble gas it does not react and is very stable.

Theoretically the valence number of the potasium would be 1, how this electron is left alone it is very reactive (the elements of the alkali metal family are not pure in nature). Note I did not draw the bohr model of this atom, I may run out of paper, however I already showed you how you can do it yourself. The electronic configuration of potassium is: [Ar] 4s1 or 1s2 2s2 2p6 3s2 3p6 4s1 (so you can do the drawing)
