a negative
a strong negative
no charge
scientists have broken down protons and neutrons into smaller particles called __________.

• 2 points

nuclei
quarks
vacuoles
isotopes

Explanation:

For the first question, positive and negative charges of equal magnitude cancel each other out. So an atom with six positive and six negative charges is electrically neutral. For the second question, protons and neutrons are composed of smaller - particles called quarks.
