There are 8 neutrons, 7 protons, and 7 electrons.
Atomitc number is always tells how many protons there are. We consider protons and neutrons to have a weight of 1. There are 7 protons, so we take the weight and subtract it from 15 to get how many neutrons we have ( which is 8). Because the atom is neutral ( no charge) there has to be the same amount of electrons as there are protons ( which is 7).

How many protons neutrons and electrons are there in a sodium atom?
Electrons~ 11 Neutrons~11 12Protons~11Youre welcome(;___________________________ (Improved answer) No, It has 11 electrons, 11 protons and 12 neutrons.
If a neutral atom has a mass of 15 amu and an atomic number of 7 whats the number of protons neutrons and electrons in the atom?
The protons is 7, the neutrons is 8, and the electrons is 22.
An atom is electrically neutral because?
An atom has no electrical charge because the negative charge of the electrons counteract the positive charge of the protons and the neutrons in the nucleus have a neutral charge. For example, Carbon has 6 electrons(-6 charge) and has 6 protons(+6 charge). Giving it an atomic weight of 12 and a charge of 0. The 6 neutrons do not change this charge, they keep it the same because they are neutral. (:
A neutral atom always has what?
Atoms are mostly empty space. They do have a nucleus. This contains subatomic particles. Protons. neutrons, and electrons are all subatomic particles. Protons carry a positive charge. Neutrons carry a neutral charge Electrons carry a negative charge. You may want to see the Bhor/plum-pudding model for more information.
What identify the number of protons neutrons and electrons in the atom.?
The number of protons and electrons is equal to the atomic number in a neutral atom.The number of protons is the mass number minus number of protons.
What are the charging of protons electrons and neutrons?
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge.
What property's do protons and electrons have that neutrons don't?
Protons and electrons are charged particles and neutrons have no charge because they are neutral.
If a neutral atom has a mass of 12 amu and an atomic number of 5 determine the number of protons neutrons and electrons in the atom.?
Protons: 5 Neutrons: 7 Electrons: 5
Is the protons for neutrons negative?
No. Protons are positive and neutrons are neutral. Electrons are negative.
What number is used to determine how many electrons are in a neutral atom?
The atomic number (the number of protons in the atom). Neutral charge = 0 = (number of protons - number of neutrons). Therefore, number of protons = number of neutrons
What electrical charge does each have electrons protons neutrons?
Electrons: Negative Protons: Positive Neutrons: Neutral
What is the number of protons neutrons and electrons in the neutral atom bromine-80?

What are protons neutrons and electrons hint charge?
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge
How many neutrons protons and electrons does a neutral atom of nitrogen- 14?
7 protons, 7 electrons and 8 neutrons
What is the electric charge of neutrons?
Neutrons are neutral, they do not have any charges on protons and electrons do.
