Question

Each set of protons and electrons represents a different atom. Place theatoms in order of their overall charge. Order them from most positive to mostnegative.1 30 protons, 26 electrons11 17 protons, 10 electrons10 protons, 10 electrons12 protons, 11 electrons

Answer 1

Firstly, we need to remember how to find the liquid charge for a single atom. We can start by saying that

`Q=n_pq_p+n_eq_e`

Where Q is the total charge, np is the number of protons, qp is the charge of a proton, ne is the number of electrons and qe is the charge of an electron

As we know, the charge of an electron is the opposite of the proton's. If we consider it as -1 and 1, respectively, we're left with

`Q=n_p-n_e`

Then, let us find the charge for each atom.

So, for our atoms, we have

`Q_1=30-26=4`
`Q_2=17-10=7`
`Q_3=10-10=0`
`Q_4=12-11=1`

Then, our answer is

`Q_2>Q_1>Q_4>Q_3`
