What information does the atomic mass of an elemt provide?
the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons
What particles make up the mass of an atom?
The number of protons
How many protons neutrons and electrons in Sc with mass number 44?
21 protons, 21 electrons and 23 neutrons
How many protons neutrons and electrons in thallium?
ThalliumSymbol: TlAtomic Number: 81Atomic Mass: 204.3833 amuNumber of Protons & Electrons: 81Number of Neutrons: 123
Is the mass of an atom made up of protons and electrons?
No protons and neutrons

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 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 is the number of protons in the necleus?
# of protons = # of electrons # of protons/ electrons + # of neutrons = atomic mass
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
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
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.
