No: They have the same atomic number but not the same atomic mass.
No, 7Be and 7Li do not have the same atomic mass. 7Be has an atomic mass of approximately 7 atomic mass units (amu) while 7Li has an atomic mass of approximately 7 atomic mass units.
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
No, carbon and oxygen do not have the same atomic mass. Carbon has an atomic mass of approximately 12 atomic mass units, while oxygen has an atomic mass of approximately 16 atomic mass units.
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
No.
No, the atomic radius and atomic mass are not the same. The atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outer electron cloud. On the other hand, atomic mass is the mass of an atom, which is the sum of the protons and neutrons in the nucleus.
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
No, the atomic number is the amount of protons it has and the weight is its mass
actually the atomic mass is the same as the amount of protons so if you want to be lazy here are the atomic number (in which is 47 also the same as the atomic mass) and the atomic mass 47, and the number of protons 47.
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
No, the atomic mass consists of protons, but the atomic mass consists of both protons and neutrons.
