an isotope
Each atom of an isotope of beryllium (or of another element) is different from the atoms of an other isotope. But all the atoms of an isotope are identical.
When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of neutrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B
No.
It depends on what isotope you are asking for, or if you are asking for an isotope at all.
The symbol of a boron atom is "B", and the number of electrons in a neutral atom is the same as the number of protons, which equals the atomic number of boron: 5.
The symbol for boron is B, and a neutral atom of boron has 5 electrons.
Boron is an element, and there are certainly atoms of boron. Saying that "boron is an atom" is a slight misuse of terminology, though.
I think that's B, the symbol for the element boron. Boron has 5 protons and 5 electrons. The most common isotope has 6 neutrons. The other main isotope has only 5 neutrons.
a regular boron atom (5B11 isotope) has six neutrons and five protons
It is a isotope of boron. Boron is a p block element.

Um. Atom? Element? If it has an equal number of protons and electrons, it has a neutral charge, so is not an ion. If it is not bonded to anything, it is not a molecule. You could call it an isotope of Boron, however this term is usually only used for less common isotopes, meaning atoms with different numbers of neutrons, and the atom with 6 neutrons is the most common isotope of Boron. Is there any more information in the question, or does anything happen to this atom?

The ion charge is typically written as a superscript to the right of the element symbol in an isotope symbol. For example, if an atom loses one electron to become positively charged, the ion charge would be indicated as a +1 next to the element symbol.
