Mass number = Number of Protons + Number of Neutrons
Mass number..can be calculated..by the sum of No. of protons and the No. of electrons. And this would give you the the mass number of the element.
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
Use avagadro's number - states the number of atoms in 1 mole of a substance: 6.022 x 10^23
To find the mass of an element in a chemical compound, you can use the atomic mass of the element from the periodic table and the number of atoms of that element in the compound. Multiply the atomic mass by the number of atoms, and you will get the mass of that element in the compound.
The mass number is the sum of protons and neutrons in the atomic nucleus.
To determine the number of moles of an element from its known mass, you can use the formula: moles = mass / molar mass. First, find the molar mass of the element from the periodic table. Then, divide the given mass of the element by its molar mass to find the number of moles.
Nitrogen is a non metal element. Mass number of it is 14.
Mass number is the number underneath the elements letter on the Periodic Table.
The mass number is the sum of protons and neutrons.
The mass number is the sum of protons and neutrons.
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
The atomic number of an element is the number of protons in the nucleus of each atom of the element. Mass number is a property of a particular isotope of the element rather than of the element itself: The mass number is the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope.
