The formula can be written, with "n" representing a number or value, as n2 or n X n.
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
the number of complications in a certain period divided by the total number of patients for the same period
A/B=X/100. A=number you are trying to calculate, B=amount which you are calculating it from, X= percentage
In A1, put the total number of symbols.In B1, put the number of symbols used.In C1, enter the formula =A1/B1Format C1 for percent and observe the answer.
A nuclide is an atomic species, having a defined number of protons, neutrons and also electrons on the orbit.
The number of protons in a nuclide is the atomic number for that element on the periodic table.
You cannot calculate but you can guess mostly by its atomic number. Studies shows that while carbon atoms mostly have 6, some are 5 or 7.
The mass number = the number of protons + the number of nuetrons. Each of these particles is considered to have a mass of 1 amu. (atomic mass unit) For example, Aluminum has 13 protons and 14 nuetrons, so it's mass number = 27.
12. When a nuclide is (properly) named in the form [element name]-[number], the number is always the mass number.
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
mass number = protons + nuetrons
20
