Bohr Rutherford diagram for magnesium

Answer 1

Lithium is element number 3
Its nucleus contains 3 protons and 4 neutrons (Atomic Mass=7) and there are 3 electrons in orbit around the nucleus.
Since there can be only 2 electrons in any orbit. the third electron orbits in a second orbital path, further out from the nucleus.

Answer 2

Inside the Nucleus:

13 Protons (13p+)

14 Neutrons (14no)

Outer Shell:

First Energy Level:

2 Electrons (2e-)

Second Energy Level:

8 Electrons (8e-)

Third Energy Level:

3 Electrons (3e-)

TOTAL OF:

13 Protons

14 Neutrons

13 Electrons

Answer 3

To draw the diagram you need to draw circles. The first circle contains 2 electrons the second contains 8 third contains 16 and the forth contains 32. Magnesium has 12 electrons. So in the first circle draw 2

Dots. Draw a circle around the first circle and put 8 dots. That's the diagram!

Answer 4

It has 2 electrons on the 1st electron shell, then 8, then 2. With 6 protons and 6 neutrons in the neucleus.
