Answer:
1. Magnesium(Mg)
2.Calcium(Ca)
3.Nitrogen(N)
4.Carbon(C)
5.Mercury(Hg)
6.Gallium(Ga)
Explanation:
1.Neutral means same no. of protons and electrons which is atomic number.So element with Atomic number 12 is Magnesium.
2. No. of protons = Atomic number.So element with Atomic number 20 is Calcium.
3.Neutral means same no. of protons and electrons which is atomic number.So element with Atomic number 7 is Nitrogen.
4.C-14 isotope has two extra neutrons making it 6+2= 8 neutrons.
5.Mercury(Hg) is the name of element.
6.Gallium(Ga) and Aluminium together belongs to Aluminium family.
