The number of neutrons in an atom can vary....ie an elements can exist with atoms that have the same number of electrons (and so are chemically the same) but have a different number of neutrons. These are called isotopes.
A neutral atom has equal numbers of elecrons and protons.
yes,,,because the number of protons is equal to the number of electrons. No, when electons are lost or gained by an atom (number of protons stays the same) the atoms become 'ions,' which are positively or negatively charged respectively.
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.
They are equal.
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
Yes , the no. of electrons is equal to the no. of protons
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
protons and electrons protons and electrons
The number of electrons should = the number of protons.
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
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.
The atomic number is equal to the number of protons and electrons, for a neutral 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.
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.
