Well, if it has got 10 electrons, it has got 10 protons....

Explanation:

And protons are the fundamental, massive, positively-charged particles that live in the nuclear core. And the number of protons gives #Z#, #"the atomic number"#, the which defines the identity of the nucleus. And so you looks at your Periodic Table, beside you now, and you tell us what #Z=10# represents.... it starts with a #"n"#...

And then you look up the first ionization energy of this element, which will be in your text or on the webz....

#underbrace(M(g)+Delta rarr M^+(g) +e^(-))_"this represents the first ionization of the element"#
