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

How do I calculate mass units?
To calculate the formula unit mass, find out the number of atoms of every element present in the chemical formula. Add together the relative atomic mass values for all the atoms of every element present.
How do u find the mass of an atom?
In an element atomic mass of an atom can be calculated by adding the mass of protons and neutrons.
What is the mass number of an atom that contains 19 protons 18 electrons and 20 neutrons?
Potassium-39 – It has 19 protons and atomic mass is 39. Hence, number of neutrons is 39 – 19 which is 20.
What is the mass number of an element that has 18 protons 18 electrons and 20 neutrons?
Because the mass number of an atom is the sum of proton number and neutron number of the atom. So, 18 + 20 = 38.
How do you find the atomic number and mass number of protons neutrons and 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 mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
How do you find the mass number on a periodic table?
An element's mass number is unique to that element, and it's listed right underneath the element's symbol in the periodic table. The mass number of an element is not the same as its atomic number.

How do you find the atomic mass of protons neutrons and electrons?
Atomic mass is the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons.
What is the charge and mass of electrons?
electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.
What is the mass number of an electron that has 18 protons 18 electrons and 19 neutrons?
Because the atomic number of an atom is same as the proton number of the atoms which means the atomic mass of the atom equal to 18. C) Correct. Because the mass number of an atom is the sum of proton number and neutron number of the atom. So, 18 + 20 = 38.
