Based on the nature of the sub-atomic particles, the correct answers are:

5. No Charge

6. Negative

7. Neutrons and Protons

8. 35 electrons

9. atomic number is 5

10. atomic mass is 11

11. number of protons is 15

12. number of electrons is 20

13. number of neutrons is 30 (55 -25)

14. mass number is 7

15. number of neutrons is 11 (36 - 25)

<h3>What are the sub-atomic particles?</h3>

The sub-atomic particles are the electrons, protons, and neutrons.

The electron is negatively-charged, the proton is positively-charged, whereas, the neutron is neutral and has no charge.

The number of electrons in a neutral atom is equal to the number of protons.

The sum of protons and neutrons gives the mass number of the atom.

Considering the given questions:

5. What type of charge does a neutron have?

Answer = No Charge

6. What type of charge does an electron have?

Answer =  Negative

7. Which two subatomic particles are located in the nucleus of an

Answer = Neutrons and Protons

8. If an atom has 35 protons in the nucleus, how many electrons will it have orbiting the nucleus?

Answer = 35 electrons

9. What is the atomic number of the atom in the diagram above?

Answer = atomic number is 5

10. What is the atomic mass/mass number of the atom in the diagram above?

Answer = atomic mass is 11

11. How many protons are in the nucleus of an atom with an atomic number of 15?

Answer = number of protons is 15

12. How many electrons are in the nucleus of an atom with an atomic number of 20?

Answer = number of electrons is 20

13. How many neutrons are in the nucleus of an atom with an atomic number of 25?

Answer = number of neutrons is 30 (55 -25)

14. What is the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons?

Answer = mass number is 7

15. How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?

Answer = number of neutrons is 11 (36 - 25)

In conclusion, the mass number of an atom is the number of protons and neutrons in the nucleus of the an atom.

Charge # = protons - electons 

Mass # = protons + neutrons 

so that would be 

3-3= charge#
3+4= mass#
