The noble gas neon has ten protons and an equal number of electrons.
Neon has 10 electrons.

An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
Oxygen has 8 protons and 8 electrons in its atom.
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
its charge is 0. Protons have a positive charge, while electrons have a negative charge (neutrons have no charge at all). So ten protons will balance out ten electrons, making the net charge 0.
The number of electrons should = the number of protons.
The charge of an atom depends on the electrons compared to protons. Electrons being negatively charged, protons being positive. If there are more protons, the atom is positive, and if there are more electrons, the atom is negative.
Generally an atom has the same number of protons and electrons. Nitrogen has seven protons.
A neutral atom with 49 electrons will have 49 protons. The number of protons and electrons are always the same in a neutral atom. If the number of protons is not matched by the number of electrons, then the atom is charged and is called an ion. Further, if protons outnumber electrons, the atom is positively charged and is a positive ion. For situations where electrons outnumber protons, the opposite is true. The element with 49 protons in it is indium, by the way.
In any neutral atom, the number of protons = the number of electrons.
An atom has the same number of electrons as it does protons, and the number of protons determines what element it is.
