What do you mean by "normal" atom?
There are ions: charged atoms or molecules. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
But I think a "normal" atom, would be a neutral one. A neutral atom has the same amount of protons as electrons, therefore have no net charge.
If you mean it by its atomic shape, its a hydrogen atom at both sides and an oxygen atom in the middle. But if you mean it by its normal appearance, then it can take up any shape.
The atomic number, which is the number of protons in the nucleus, determines what kind of atom it is.
In a normal atom there are 1 electron, but some are different.
The number of protons defines what element the atom is, and it also defines how many electrons the atom has in its various orbitals in a normal state.There is one electron per proton in an atom in a normal state.
no
They are not always the same. It helps the atom be balanced.
It is very unusual for one kind of atom to become another kind atom, however it does happen in radioactive processes. Every element is characterized by a distinct number of protons. For example, all hydrogen atoms have 1 proton, all helium atoms have 2 protons, etc. Atoms also include electrons and neutrons. However, adding or removing electrons or neutrons does not change the kind of atom. For example, a helium atom with 2 electrons or 1 electron is still a helium atom. Alpha decay is an example of a radioactive process in which the number of protons changes (and therefore the kind of atom changes). An alpha particle includes 2 protons and 2 neutrons. When it is expelled from an atom, a new kind atom is formed. This occurs when a uranium atom (92 protons) is changed into a thorium atom (90 protons) + an alpha particle.

this sucks
This atom become a cation (positive).
An atom is the smallest piece of an element that can be identified as that element.
The hydrogen atom has 1 electron.
