Question 2 of 10

Attempt 1 of 2 (2 points possible)

Ordering: Use the up and down arrows to order the list and then click "submit."

Each set of protons and electrons represents a different atom. Place the atoms in order of their overall charge. Order them from most positive to most negative.

30 protons, 26 electrons

17 protons, 10 electrons

12 protons, 11 electrons

10 protons, 10 electrons

Solution:

Protons give +(positive charge), electrons - -(negative charge)

So,

30 protons, 26 electrons = +30 – 26 = +4;

17 protons, 10 electrons = +17 – 10 = +17;

12 protons, 11 electrons = +12 – 11 = +1;

10 protons, 10 electrons = +10 – 10 = 0;

Order them from most positive to most negative:

1. 17 protons, 10 electrons

2. 30 protons, 26 electrons

3. 12 protons, 11 electrons

4. 10 protons, 10 electrons
