Atomic number means the number of protons. It doesn't make any sense that an atom has -1 protons. So, there's no atom which has an atomic number of -1.
However, in nuclear decays, some particles, such as the beta-minus particle, have this symbol : -10Beta.
So you see, you might think that a beta particle has a proton number of -1, but this is not true. The -1 simply shows the charge on the beta particle, to make it easier to balance the nuclear decay equations.
Hydrogen is a non metal element. Mass number of it is 1.
ermm.....
H
Hydrogen
1
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has
Hydrogen-1, the most abundant isotope of hydrogen, has a mass number of 1. It has one proton and no neutrons.
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
noo i think

The element hydrogen and more specifically its isotope, protium or 1H1
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
