What is the mass of protons and nuetrons?

Protons and nuetrons have a larger mass than an electon.

It is 19. The mass of an atom is equal to the total sum of the nuetrons and protons in the atoms nucleus.

No. Protons and neutrons have about the same mass but electrons are much lighter.

it has 35 nuetrons, 30 protons, and 30 electrons with a mass of 65

== The equation of atomic mass is protons+nuetrons== atomic mass. ===

Mass number will help you. Mass number is the total of neutrons and protons.

mass number = protons + nuetrons

Protons and nuetrons Dom says: Protons and Neutrons.

Protons and neutrons have about the same mass, but electrons are much, much lighter.

To calculate the atomic mass of an element, add up the mass of protons and nuetrons.

6 protons and 6 neutrons

no. of protons+no. of nuetrons in an atom is known as mass no. of that atom. while no . of protons present in an atom is called its atomic no. thus, in 1st condition we consider both, no. of protons as well as no. of nuetrons and in the 2nd condition we just consider no. of protons.

most of the time there are two but if you have a positively charged atom there are just more protons than electrons or neutrons MASS IS ALWAYS PROTONS PLUS NUETRONS SO IF YOU KNOW THE MASS # AND THE NUETRON # AND SUBTRACT NUETRONS FROM MASS YOU GET THE PROTON # ALSO THE PROTON # = TO THE ELECTRON # AND THE ATOMIC #

2 Protons and 2 Nuetrons

The sum of the number of protons and the number of nuetrons.

atomic number is the number of protons. the sum of protons and neutrons is known as mass number

The number of protons for any element is the atomic number. The number of electrons is equal to the number of electrons. To find the number of nuetrons you must subtract the atomic number from the mass number mass number-atomic number= number of nuetrons protons=electron the number of protons in the element aluminum is 13. The number of electrons is 13.

The total number of protons and neutrons in an atoms is the mass number of the atom.

well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.

since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons

The mass number = the number of protons + the number of nuetrons. Each of these particles is considered to have a mass of 1 amu. (atomic mass unit) For example, Aluminum has 13 protons and 14 nuetrons, so it's mass number = 27.

no. -------------- In atoms, only the Protons count as atomic number The neutrons and the protons together is as the atomic mass

Sodium is a metal element. Mass number of it is 23.

Hydrogen has 0 neutrons. Mass (protons + neutrons) - Atomic number (protons) = number of neutrons.

protons and nuetrons are equal to no. of electrons present in atom
