To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number. number of neutrons = mass number - atomic number.

The atomic number of the element equals the number of protons. Calculating the number of neutrons then becomes atomic mass of the isotope minus the atomic number of the element equals the number of neutrons.

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge.

Here, mass number is 27 and there are 14 neutrons hence protons=27-14=13. In a neutral atom, number of protons=number of electrons. Hence in this case the number of electrons in the neutral atom will be 13. Now, since the atom carries +3 charge hence it will have 13-3=10 electrons.

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. ... The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

The atomic mass of an element is the total number of protons and neutrons in the nucleus of the atom. The mass number is used to calculate the number of neutrons & electrons in one atom of an element. In order to calculate the number of neutrons you must subtract the atomic number from the atomic mass.

Protons, neutrons, and electrons: Both protons and neutrons have a mass of 1 amu and are found in the nucleus. However, protons have a charge of +1, and neutrons are uncharged.

Explanation: You can simply subtract the atomic number from the mass number in order to find the number of neutrons. If the atom is neutral, the number of electrons will be equal to the number of protons.

Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred as mass number (Also, called as atomic mass). So, to determine the number of neutrons in atom, we only have to subtract the number of protons from the mass number.

Chromium 53: The atomic number Z = 24, so there are 24 protons and 24 electrons. Number of neutrons = A – Z = 53 – 24 = 29.

(a) Magnesium has atomic number 12, so all atoms of magnesium contain 12 protons and 12 electrons. The three isotopes are therefore represented by Mg, Mg, and Mg. (b) The number of neutrons in each isotope is the mass number minus the number of protons.

Explanation: Boron has 5 protons, 5 neutrons and 5 electrons. The atomic number (also known as the proton number) of Boron is 5 as it has 5 protons. It has a mass number of 10, as protons and neutron have a relative atomic mass of 1 each, and a neutral charge, as there are equal numbers of +1 protons and −1 electrons.
