Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
always associate an electron as -
An electron is negative. Think electron think the symbol -  minus. electron. minus. -

Ah!  I hope I get this right:

where I see a - sign, it means "electrons".  If I see a + sign and a - sign, I can imagine a line running from the plus to the minus: the electrons are over at the - end because - means 'electron(s)'.

A + atom has less electrons than when it was neutral--it's proton to electron balance is skewed.  There are more protons than electrons (in a single atom)

A - atom has extra electrons.  There are more electrons than protons.

In a pair, with either ionic or covalent bonding, + and - tell me which atom in the pair has the most electrons  above its natural (pure element) count.

So I need to have the electron counts memorised for each atom--the valence electrons--or the bonding electrons...

But...the + and the - are the answer: the atom with the minus has more electrons than normal when compared to the atom with the plus.  (Or: the atom with the plus has less electrons than normal when compared to the atom with the minus)
