What particles make up the mass of an atom?
The number of protons
What is determined the mass of an atom?
Protons, neutrons and electrons
Is the mass of an atom made up of protons and electrons?
No protons and neutrons
What particle determines the mass of a atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
What particles make up the mass of an atom?
The number of protons
How are protons and neutrons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
How are electrons and protons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
What determine the mass and an atom?
Protons, neutrons and electrons
What is determined the mass of an atom?
Protons, neutrons and electrons
Is the mass of an atom made up of protons and electrons?
No protons and neutrons
What is the mass of an atom that has 10 protons 13 neutrons 10 electrons?
The mass number of this atom is 23, the sum of the number of protons and neutrons.
How many protons electrons and neutrons does an atom have?
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
The particle that determines the mass of the atom is what?
Protons, neutrons and electrons
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
What is the mass of an atom that has 92 protons and 108 neutrons?
If you have 92 protons and 108 neutrons you will get 200 electrons
