How many electrons does neon have?

Redirected from "Suppose that I don't have a formula for #g(x)# but I know that #g(1) = 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

#10# electrons

Explanation:

The number of electrons is equal to the number of protons.
The number of protons is equal to the atomic number #=># the number you see in the upper left corner.

The atomic number of Neon is #10# #=># it has #10# protons and #10# electrons.

The only difference is that electrons are negatively charged and protons are positively charged.
