The mass of an atom equals to the number of protons and 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 atomic number of 7 indicates the number of protons, which is 7. Since the atom is neutral, the number of protons also equals the number of electrons, so there are 7 electrons. To find the number of neutrons, subtract the atomic number from the mass number: 15 (mass number) - 7 (atomic number) = 8 neutrons.

Mass number - atomic number equals?

Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.

N atom has 7 protons and a mass number of 14 What is the number of neutrons in an atom of N?

The mass number of an atom is the sum of its protons and neutrons. In this case, nitrogen (N) has 7 protons and a mass number of 14. So, the number of neutrons in an atom of nitrogen is 14 - 7 = 7 neutrons.


When is an atom neutral When mass number equals number of protons equals number of electrons or when atomic number equals number of protons equals number of electrons?

An atom is neutral when the number of protons in the nucleus equals the number of electrons surrounding the nucleus. This means that the atom has no overall charge, as the positive charge of the protons is balanced by the negative charge of the electrons. The mass number, which is the sum of protons and neutrons, does not necessarily impact the neutrality of the atom.


What is the number of an atom with 5 protons and 7 neutrons?

To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
