Atomic Mass is the mass of an atom, typically expressed in atomic mass units (amu). It is a weighted average of the mass of an atom's isotopes, taking into account their relative abundance in nature. It is usually found on the Periodic Table beneath the chemical symbol of each element.

How do you use atomis mass in a sentence?
The atomic mass gives the mass of the atom. It is one of the physical property of the atom.
What was lithiums atomis number?
Li is atom number three, not only 'was' but it still is and ever will be.
Robert millikan's major contributions to the atomic theory?
Millikan: He discovered that the weight of an electron is 1840 times smaller than a hydrogen atom (atomis mass of 1) Thomson: Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which called electrons
What properties stay the same during physical and chemical change?
mass mass
Is the atomic mass and atomic number the same number?
An Isotope of an element is an atom that has the same number of protons, (number of protons is the defining feature of an element) but different number of neutrons.Because The mass number is the sum of protons and neutrons, different isotopes have different mass numbers.
What is weighted average mass of an element isotopes?
average atomis mass
How do you use atomis mass in a sentence?
The atomic mass gives the mass of the atom. It is one of the physical property of the atom.
Which element has 10 neutrons is a nonmetal and has an atomis mass greater than 19?
Neon
Is the mass number and the atomic mass the same?
No, the Atomic Mass is the full complete mass while the mass # is just the whole number. For example: carbon's atomis mass is 12.011 and the mass # is 12.
Why deutrium oxide is heavier than water?
Because deutirium has a neutron.So its atomis mass is double as protium.Both form water.But different in mass
What was President Trumans main argument for using the Atomis bomb against the Japanese?
Atomic not Atomis!
What did Millikan contribute to atomic theory?
He discovered that the weight of an electron is 1836 times smaller than that of a hydrogen atom (atomis mass of 1)
The weighted average of the masses of all the naturally occurring isotopes of an element is the what?
Atomic weight or atomic mass used in stoichiometric calculations.
What is the atomis weight of silver?
the answer is 107.87
Why is the atomis mass of sodium 22.99?
The atomic mass of sodium is 22.99 because it is an average mass of all the naturally occurring isotopes of sodium, taking into account their abundance in nature. Isotopes are atoms of the same element with different numbers of neutrons, which affects the overall atomic mass.
The eternal motion of atoms is called what?
Atomis
Which element has an atomis number of 13?
Aluminum (Al)
