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.
The atomic number of an element is equal to the number of protons in its nucleus. The atomic weight is the average mass of an element's isotopes, taking into account their relative abundance. Both the atomic number and weight can be found on the periodic table for each element.
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
The atomic number reflects the charge number of the nucleus. It is always equal to the number of protons found in the nucleus.
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
In an uncharged atom, the number of electrons is always equal to the atomic number, in this instance, 9.
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.
The atomic mass of an element is equal to its molar mass in grams/mol.
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!
