Explanation:

Step1: Recall atomic - structure facts

Atomic number = number of protons. In a neutral atom, number of electrons = number of protons. Atomic mass = number of protons+number of neutrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Protons and neutrons are in the nucleus, electrons are in the electron - cloud outside the nucleus.

Step2: For questions 4 - 14

1. Protons have a positive charge.
2. Neutrons have a no (neutral) charge.
3. Electrons have a negative charge.
4. Protons are found in the nucleus.
5. Neutrons are found in the nucleus.
6. Electrons are found in the electron - cloud, located outside of the nucleus.
7. Protons and neutrons are added together to find the atomic mass.
8. The atomic number tells me how many protons there are.
9. Electrons are much smaller than protons and neutrons.
10. Protons, neutrons, and electrons are sub - atomic particles.
11. An atom is the smallest unit of matter that retains the properties of an element.

Since the images of the atoms are not provided, we cannot fill in the values for atomic mass, atomic number, number of protons, neutrons, electrons, and element ID for questions 1 - 3.

Answer:

1. positive
2. no (neutral)
3. negative
4. nucleus
5. nucleus
6. electron - cloud; outside
7. Protons; neutrons
8. protons
9. Electrons; protons; neutrons
10. sub - atomic particles
11. the smallest unit of matter that retains the properties of an element
