Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
The symbol is Ba. The number of neutrons equal the number of protons.
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
The number of protons
The number of protons and neutrons is not equal. The equality is not a rule.
Atomic number = number of protons + number of neutrons Mass number = number of protons + number of neutrons
Mass number is about the neutrons and protons. The total of neutrons and protons.
The symbol is Ba. The number of neutrons equal the number of protons.
The mass number is the average atomic mass of all the isotopes that are found in nature.
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
The mass number is the sum of protons + neutrons.
25 is the number of protons and neutrons added together. The atomic number of Mg is 12 which is the number of protons. So 25 - 12 = 13 neutrons.
Mass number = Protons+Neutrons
Mass number!:)
The 46 = #Neutrons + #Protons and 22 = #Protons so... # Neutrons = 26
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
