Isotopes
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
You would subtract the atomic number from the mass number.
The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.
Not much. Phosphorus, atomic number 15, has an average atomic weight of about 31, indicating that most phosphorus atoms already have 16 neutrons.
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
The mass number will change. Mass number - Atomic number = Number of neutrons. So, if the number of neutrons change the mass number will change. The atomic number would not change because the atomic number is equal to the number of protons and if the number of protons change, then the element would change.
Yes. Atoms with a different number of neutrons are called isotopes of that atom, but a variation in the number of neutrons does not change what the atom is.
Atomic numbers are determined by the number of protons an atom has. The mass number is determined by the number of protons and neutrons. While the number of protons can't change (as the element itself would change), neutrons can and do vary. These are called isotopes.
The neutron has no charge so changing the number of neutrons in the nucleus would not change the charge of the nucleus.
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
You would subtract the atomic number from the mass number.
How many neutrons would it have if it had 11 neutrons? 11.
The number of neutrons in any element is equal to mass number - atomic number. So,number of neutrons in cobalt is = 58 - 27 = 32. therefore, number of neutrons in cobalt is 32.
A negative oxygen ion still has 8 neutrons, just like a neutral oxygen atom. The number of neutrons in an atom is determined by the element's atomic number, which for oxygen is 8. Changing the number of protons would change the element itself, not the charge of the ion.
If the number of protons changes, the atom becomes an entirely different element. Changing the number of neutrons creates isotopes of the same element, which can have different properties. Changing the number of electrons alters the atom's charge, turning it into an ion.
Neon-20 has 10 neutrons. Neon's atomic number is 10, which means it has 10 protons. To calculate the number of neutrons, subtract the atomic number from the atomic mass. Neon-20 has an atomic mass of 20, so it must have 10 neutrons.
The number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
