Where can we find atomic weight?
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.
What does the atomic number 28 mean?
Nickel
Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile.
Why is silicon 28 more abundant?
Because most Si atoms have a mass of 28 amu, the average mass of all silicon atoms is very close to 28.
How many protons and neutrons does silicon 28 have?
For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28.
What is the atomic weight of gold?

What is atomic weight?
Atomic weight, also called relative atomic mass, ratio of the average mass of a chemical element’s atoms to some standard.
What is the atomic mass of 28 silicon?
Silicon exists in nature as a mixture of three isotopes: 28 Si, 29 Si and 30 Si. The atomic masses of these nuclides are known to a precision of one part in 14 billion for 28 Si and about one part in one billion for the others.
What is the atomic weight of an oxygen atom?
Atomic weight. The unit of atomic mass was thereby defined as 1/16 the mass of an oxygen atom. In 1929 it was discovered that natural oxygen contains small amounts of two isotopes slightly heavier than the most abundant one and that the number 16 represented a weighted average of the three isotopic forms of oxygen as they occur in nature.
What is atomic mass of an element?
The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. (Atomic mass is also referred
