What is the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
How do you find atomic mass in an atom?
the atomic mass is on some periodic tables and is the decimal. for example... for carbon the atomic mass is 12.01 on my periodic table that i am looking at go to this website. http:/www.ptable.com. it should have a periodic table and the atomic mass is on the very bottom of each box. for example the atomic mass for bromine is 79.904
How is the mass number different from the average atomic mass?
The mass number is the total number of protons and neutrons in an atom's nucleus, while the average atomic mass is the weighted average of the masses of all isotopes of an element based on their abundance in nature. The mass number is a whole number, while the atomic mass is a decimal value.
What the distinction between atomic mass and atomic number?
the number of positive charges or protons in the nucleus of an atom of a given element, and therefore also the number of electrons normally surrounding the nucleus. (atomic number) The mass of a given atom or molecule, expressed in atomic mass units. (atomic mass)
What is the molecular mass of allegra C32H39NO4 HCl to 2 decimal places?
The molecular mass of allegra (fexofenadine hydrochloride) is calculated by adding the atomic masses of each atom in the compound. By summing the atomic masses of C32H39NO4 HCl, the molecular mass of allegra is 538.63 g/mol, to two decimal places.
What is the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
What does the decimal number in an element key represent?
atomic mass
What does the decimal tell you in an atomic mass?
that there are stable isotopes of that element
Why atomic mass is always a whole number but atomic weight may be a decimal number?
Atomic mass is the total mass of protons and neutrons in an atom, which are whole numbers. Atomic weight, on the other hand, takes into account the abundance of different isotopes of an element, which can result in a weighted average that may be a decimal number.

What To two decimal places what is the relative atomic mass and the molar mass of the element potassium K?
It is 38.96
What is the two decimal places of relative atomic mass and the molar mass of the element potassium K?
It is 39.10
What is atomic mass of zinc rounded to 1 decimal point?
65.465.465.465.4
in an element box what does the number with a decimal stand for?
The number with a decimal in an element box represents the average atomic mass of the element. It is calculated based on the abundance of each isotope of the element in nature.
