Helium is a non metal element. Atomic mass of it is 4.
Helium's atomic number is 2.
Hydrogen has atomic number 1 whereas helium's is 2.
Atomic weight: the atomic weight of an chemical element, in atomic mass units or gram atomic mass Atomic mass: the atomic mass of an isotope, in atomic mass units or gram atomic mass Molecular mass: the mass of a molecule, in atomic mass units or gram molecular mass
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
atomic number is a number atomic mass is a mass
The atomic mass unit is used to express the measure of the atomic mass.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
3 times, heliums mass is 4 and carbons mass is 12
The atomic mass is the same as the atomic weight therefore it is 9.01218. Beryllium is a non metal element. Atomic mass of it is 9.01. The atomic mass number, which is distinct from the atomic mass and the atomic weight, is 9.
The atomic mass of hydroxide (rounding) is 17.008 atomic mass of oxygen 16.00 + atomic mass of hydrogen 1.008
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Atomic mass = Mass of protons + Mass of neutrons
gas is heliums only state of matter
The atomic mass for Aluminum is 26.98 atomic mass units or amu.
The atomic mass of mercury is 200.59 amu (atomic mass units).
Silicone has that atomic mass. Atomic mass number is 28.
the atomic mass of a (item) is (atomic mass of the item).
The Atomic Mass is the weighted average mass of the isotopes of an element
The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
Atomic number = Number of protons Atomic mass = Mass of protons + mass of neutrons
