The mass number has to be greater then the atomic number because the mass number is the protons plus the neutrons. If you were to take 10-12 you would get a negative number of 2 and there can't be a negative number of neutrons!
No. The atomic number only counts the number of protons or electrons in an atom, but the mass number counts at least the number of protons, sometimes the electrons and the number of neutrons if any. The closest they will get is being the same (Hydrogen with AN=1, MN=1), but the mass number will almost always be bigger than the atomic number.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
Atomic Number = 5 Atomic Mass = 10.811
Silver is a meta element. Atomic mass of it is 107. Atomic number of it is 47.
The atomic number is the smaller of the two numbers shown in the periodic table. It represents the number of protons in the nucleus of an atom and determines the element's identity. The larger number, the atomic mass, is the sum of protons and neutrons in the nucleus.
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.
The 'standard' hydrogen atom has atomic number 1, atomic mass 1, no neutrons. Although there are 2 other isotopes of hydrogen: - (cant confirm name) which has atomic mass 2 and 1 neutron. - (cant confirm name) has atomic mass of 3 and 1 neutron. All isotopes have atomic number 1.
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
In the atoms on the periodic table the atomic number is the smaller of the two numbers, the other larger number is the mass umber
In chemistry, the smaller number typically refers to the atomic mass, which is the weighted average of the masses of an element's isotopes. The larger number usually represents the number of protons in the nucleus of an atom, known as the atomic number. The atomic number determines an element's identity on the periodic table.
it depends which number you are referring to. in the periodic table, the numbers referr to number of protons and then relative atomic mass. the larger number is relative atomic mass and the smaller number is the number of protons for example, chlorine, has a relative atomic mass of 35.5 and a proton number of 17
Atomic mass includes the total mass of protons, neutrons, and electrons in an atom. Since protons and neutrons contribute significantly to the mass of an atom, atomic mass is generally greater than atomic number, which represents the number of protons in the nucleus. Electrons have a much smaller mass compared to protons and neutrons, so they have less impact on the overall atomic mass.
take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the atomic mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.
Boron has a larger atomic radius but a smaller atomic mass.
No. The atomic number only counts the number of protons or electrons in an atom, but the mass number counts at least the number of protons, sometimes the electrons and the number of neutrons if any. The closest they will get is being the same (Hydrogen with AN=1, MN=1), but the mass number will almost always be bigger than the atomic number.
83.98 amu is the Atomic Mass, 36 is the atomic number.
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
