An atom with an equal number of electrons and protons has no net electrical charge, as the number of positive (proton) and negative (electron) charges are balanced.
A neutral atom has equal numbers of elecrons and protons.
The number of electrons should equal the number of protons, otherwise you have an ion.
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
They are equal.
In a neutral atom the number of protons is equal to the number of electrons. And by definition the atomic number of an atom is equal to the number of protons in it. So the atomic number of a neutral atom is equal to the number of protons or the number of electrons in the atom.
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
A neutral atom has equal numbers of elecrons and protons.
The number of electrons should = the number of protons.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
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.
The number of electrons should equal the number of protons, otherwise you have an ion.
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
No - in fact it is quite rare
In a normal atom, the number of protons is equal to the number of electrons. This balance is necessary for the atom to be electrically neutral.
