This is stating that, if x was 2, what is the answer to the equation.
So basically, the equation is 2^2 - 2(2) = ?
The first step is 2 squared, which is 4, then you subtract 2(2) or 4. So 4-4 is 0.
The value of f(2) is 0
A would be correct.
There in an increase in reactivity because the nonmetals want to hold on to their electrons.
<h3>Reactivity</h3>
With less electronegativity, there is also less ionization energy. For metals, it is easier to lose the electrons, hence the metal becomes more reactive because it uses less energy.
For nonmetals, they are gain electrons and not lose them. Thus, an increase in electronegativity and ionization energy means an increase in reactivity because the nonmetals want to hold on to their electrons.
