1 Electronegativity is the ability of an atom to attract electrons.
Explanation:
It's how many are in the element's outer layer. The layers go: 2, 8, then 8.
Ex-6 electrons. 1 layer is 2, the next layer has 4 left. If that layer holds 8, you can do 8-4 and it has 4 valence electrons.
Ex-10 electrons. 1 layer is 2, the next layer has 0 left. It has 8 valence electrons because the outermost layer is full with 8.
ex-11 electrons. 1 layer is 2, the next layer is full as well. 2+8=10; it has 1 left. So that element has only one valence electron.
2h 42m = (2+42/60)h = 2.7h
80mi/h x 2.7h = (80*2.7)mi = 216mi
