How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
Smallest known particle that makes up protons and neutrons?
Of those three the electron is the least massive.
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
How many neutrons and electrons are in the element americium?
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
What is the atomic particle that has an extremely small mass compared to the others?
Of the 3 atomic particles protons, neutrons and electrons, electrons have the smallest mass.
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
What is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
What has the smaller mass protons electrons or nutrons?
Electrons have a smaller mass than both protons and neutrons. Both protons and neutrons are over 1800 times as massive as electrons.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
How are protons and neutrons related?
For a stable atom, no. of protons= no. of electrons no of neutrons= Atomic Mass- no. of protons
What particles make up the mass of an atom?
The number of protons
How many protons electrons and neutrons does americium have?
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number 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 plus what determines the atomic mass?
protons plus neutrons
The neutrons in an atom have the least amount of mass?
No actually, the neutrons and the protons of an atom are relatively the same in mass. Electrons have the smallest mass in an atom, and are not even considered when we look at the mas sof an atom.
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
