No.
The atomic number is dependent on the number of protons. The atomic weight is dependent on the number of protons and neutrons. As almost every element has some neutrons in its nucleus the atomic number will never be equal to the atomic weight.
The one possible exception is Hydrogen with a single proton. However there are two isotopes of hydrogen: deuterium and tritium. Deuterium has one proton and one neutron. Tritium has one proton and two neutrons. Therefore when taken as a whole the atomic weight of hydrogen will always be slightly greater than 1g/mole.
Atomic weight/ mass = number of protons + number of neutrons
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
The atomic mass doesn't equal to the number of protons. The number of protons plus the number of neutrons equal to the atomic weight... DAI BI!
Electrons or Protons. As they are effectively equal in no in a neutral atom.
Mass
atomic weight = mass of protons + mass of neutrons
Atomic number is always equal to the number of protons in an atom.
Atomic weight/ mass = number of protons + number of neutrons
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
The number of protons in the nucleus of each atom that has the atomic number.
Atomic weight of an element is the number of protons plus neutrons in the nucleus, atomic number is the number of protons only.
atomic weight
It is called the atomic no. of element. It is also equal to the no. of electrons in the atom.
Electrons are equal to the number of protons and the atomic number. To find the number of neutrons you must subtract the atomic number from the mass number.
