Ialways you guys out now me or im going to there are three known forms of hydrogen. these forms are called (ions/copies/isotopes) of each other. each of these forms will have the same number of (neutrons/electrons/protons) but different numbers of (protons/neutrons/electrons) in their nuclei.

There are three known forms of hydrogen. These forms are called isotopes of each other. Each of these forms will have the same number of protons but different numbers of neutrons in their nuclei.

Explanation:

when an element of an atom have same atomic number but different mass number it is said to be an isotopes. The disparity in mass number is due to the difference in the neutron number. Mass number is determined by the sum of proton number and neutron number . The proton number is same as the atomic number. The changes in the neutron number most notably affect the physical properties of the atoms.

Proton and neutron are found in the nucleus of an atom and they determine the weight of an atom . Isotopes can be said to be when an atom of element have different neutron number. Example is hydrogen that has 3 isotopes namely hydrogen, deuterium and tritium. They have mass number of 1, 2 and 3 respectively . The difference in mass number is because of their difference in neutron number but all of them have the same proton number .

explanation:

go away, people want answers, not to hook up

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
