What is a positive charge?

200

This is just slightly more massive than a proton and about 1838 times the mass of an electron.

What is a neutron?

200

The periodic table has this many periods.

What is a nonmetal?

200

All the elements in this will have the same electron dot configuration.

What is family/group?

300

An anion occurs when an element does this.

What is gain an electron?

300

Potassium-40 is different from potassium-38 because it has a different number of this.

300
Elements in the same family on the periodic table have the same number of these.

What are  valence electrons?

300

Atomic radius affects this.

What is electronegativity?
300

Going across a period, each element will increase by this.

What are valence electrons?

400

An anion has this type of a charge.
