Physics, Atoms??

Question

So, what different types of atoms are there???

Answer 1

That depends on what you mean by "type." Each atom (hydrogen, helium, lithium, etc) is "different" from another in that it will have a different number of protons, neutrons and electrons. For instance, a hydrogen atom has one electron and one proton. The helium atom has two electrons, two protons and two neutrons. So far, almost 120 atoms have been discovered.

Atoms can also form ions where they gain or lose electrons, but the number of protons and neutrons remain the same. Atoms can also form isotopes, which have the same number of electrons and protons, but a different number of neutrons than normal. There is an almost infinite number of ions an isotopes out there.

Answer 2

If you want to focus on atoms (neutrally charged), then there are two ways they can differ.

Possible Difference 1:
Atoms with different numbers of protons in the nucleus correspond to different elements. The atomic number of an element tells you how many protons there are in the atomic nucleus. If two atoms have different numbers of protons, they are two different elements.

Possible Different 2:
Even atoms within the same element (same number of protons) are not always alike...they can still vary based on the number of neutrons in the nucleus. Atoms with equal numbers of protons in the nucleus but with different numbers of neutrons are called isotopes. For each element, multiple isotopes exist. For example, Hydrogen has 3 isotopes, Hydrogen-1, Hydrogen-2, and Hydrogen-3, with 0, 1, and 2 neutrons in the nucleus respectively (but all have just 1 proton).

The only other way for "atoms" to differ (notice the quotation mark) is by the number of electrons to differ. But if the number of electrons differs from the number of protons in the nucleus, the atom has a net charge and is therefore an ion (not an atom).

Answer 3

we have different type of atoms,
it depends on the subatomic particle; how many electron, proton and neutron are there in the atom. This is the very simple respond although I think that is enough.
these differences has been found and developed by Dimitry Evanovich Mendeleev (I'm not sure about dictation).
