atomic mass and atomic number?

Question

ok
what does the atomic number represent?
nubmer of electrons?protons?neutrons?


and what does the atomic mass represent?
electrons?neutrons?protons?

plz answer soon

Answer 1

atomic number = number of protons

atomic mass = number of protons + number of neutrons

Answer 2

Atomic Number Represents

Answer 3

Atomic Mass=Number of Nutrons+Number of Protons
Atomic Number=Number of Protons

Answer 4

Ok.
atomic number represents the number of protons and electrons
and the atomic mass is just the mass

if you want to find the number of neutrons in an element u round the atomic mass to the nearest whole number and subtract the atomic number from it.

Answer 5

The Atomic Number Indicates

Answer 6

Additionally, the atomic mass is used to denote the mass of one mole of the most common species of that element. (A mole being ~6.022x10^23)

Generally, atomic mass is expressed in amu or atomic mass units.

The atimic numbr expresses the number of protons contained in an atom. It is to be noted, that not all elements incorporate neutrons on a 1:1 ratio to protons, nor does the number of electrons always match the number of protons, due to the existence of positive and negative charges.

Answer 7

1)The number of protons in a nucleus is called the atomic number and always equals the number of electrons in orbit about that nucleus (in a nonionized atom). Thus, all atoms that have the same number of protons--the atomic number--are atoms of the same element. 2)The atomic mass is the total mass of protons, neutrons and electrons in a single atom. 3)The total weight of an atom is called the atomic weight. It is approximately equal to the number of protons and neutrons, with a little extra added by the electrons for nucleus.

Answer 8

the atomic number represented the number of protons and electrons.
The atomic mass represents the mass of the protons and neutrons. To find the number of neutrons, subtract the atomic number from the atomic mass.
the atomic mass is based on the average of isotope abundance in nature. remember that atomic mass and mas number is different ;]

Answer 9

the atomic number represents the number of protons in an element and if it is a neutral element (as they are represented on the periodic table of elements) then it also represents the number of electrons.

the atomic mass is an average of all the atomic masses of the isotopes of an element. to determine the atomic mass of an isotope add the number of protons and the number of neutrons together.
