Which statement about the atomic nucleus is correct?

3. The nucleus is made of protons and neutrons and has a positive charge.

4. -2 • -1 • 0 • +1 The charge of an electron is

5. -1

6. Have an equal number of charged and noncharged particles. • Have neutrons in their nuclei. • Have an equal number of electrons and protons • Have an equal number of neutrons and protons. Atoms are neutral because they

7. Have an equal number of electrons and protons

8. The number of protons in the nucleus. • The electric charge of the nucleus. • The number of neutrons in the nucleus. • Atomic mass. The order of elements in the periodic table is based on

9. The number of protons in the nucleus

10. Protons. • Neutrons. • Valence electrons. • Protons and neutrons. Atoms of elements that are in the same group (column) have the same number of

11. Valence electrons

12. Eight neutrons in its nucleus • A total of eight protons and neutrons. • Eight protons in its nucleus. • A total of eight neutrons and electrons. Oxygen has atomic number 8. This means that an oxygen atom has
