How do you draw the lewis dot diagram for beryllium?

Answer 1

In your nucleus you should include the number of protons and neutrons. The number of protons can be found in the Periodic Table as the atomic number. To get the number of neutrons, subtract the protons from the Atomic Mass.

Next, you draw the orbitals, and their respective electrons. Remember the number of electrons in each orbital.

1st orbital-2 electrons

2nd orbital- 8 electrons

3rd orbital- 18 electrons

Answer 2

You take the atomic Number...Then before you subtract 'estimate' your atomic mass and then subract your atomic number from your estimated atomic mass and you get your nuetrons. or w.e. then draw a circle put 2 dots on the line of the circle and make more and more rings until you get to the number of nuetrons you had..by the way 2 the first circle has count,,( First circle can hold 2 charges and the 2nd and 3rd rings around it can hold 8)

Answer 3

Since beryllium only has 2 valence electrons (4 in all, minus the full s-orbital), you would just draw a pair of electrons anywhere around the atomic symbol, like this:
