How can you get atomic mass?
Pick up a periodic table. There are numbers above and below each element. Eg, carbon will have a 6 (atomic number) and 12(.011). The 12.001 is Carbon's mass. If it is molecular mass, it involves adding the atomic masses together. And remember, say if it is O2 you add it twice because there are two of that element.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the formula of a molecule of oxygen?
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol
The atomic mass is the?
The expression atomic mass is used only for isotopes; the atomic mass is the mass of an atom expressed in unified atomic mass units - (1 amu = 1/12 atomic mass of carbon-12).For elements the expression is atomic weight; the unit is the same.
What is the atomic name of oxygen?
I think its O2
What is the atomic mass for chlorine?
Atomic Mass: 35.453
What is the atomic mass in carbon?
The Atomic mass Is 12
What relationship exist between the atomic mass and the isotopes?
When atomic mass is expressed in unified atomic mass units, it is similar to isotopic mass and has the same numerical value as that of atomic mass. The atomic mass or the relative isotopic mass is the mass of one atom which at a time can be only one isotope.
The atomic mass of an atom is equal to the sum of numbers of what?
protons + electrons= atomic mass NUMBER, not the atomic mass.
Does atomic mass has a positive change?
No. Atomic mass is a measure of mass, not charge.
Why is atomic mass represented by A?
It is not, The mass number is (A). The symbol for atomic mass is (ma)
What is atomic mass and the number of calcium?
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
