ok so first you look at the atomic #. For helium that is 2. that is the number of protons, and electrons are the same # of protons . long story short, the atomic # is the number of protons which r the # of electrons
The number of electrons should = the number of protons.
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 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.
In any neutral atom, the number of protons = the number of electrons.
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 atomic number of an atom gives the number of protons in its nucleus, which also determines its unique identity as an element. It also indirectly gives the number of electrons in a neutral atom, as the number of protons is balanced by the number of electrons in the atom.
The number of protons in an atom determine what element it is, while the number of electrons is what gives it it's electric charge (positive, neutral, or negative. i.e. if there are 5 protons and 5 electrons, the atom will have a neutral charge.
The atomic number gives you the number of electrons and protons there are in an atom. ex: Carbon (C) has atomic number 6. So we know that it has 6 protons and 6 electrons
In any atom, the number of protons will equal the number of electrons, but only in a neutral atom. Remember that most atoms loan, borrow or share electrons, so the number of protons will not be equal to the number of electrons in all cases. In review, only in a neutral atom will the number of protons equal the number of electrons.
The atomic number is equal to the number of protons in an atom, which also corresponds to the number of electrons in a neutral atom. This means that the atomic number gives you the total number of electrons in a neutral atom of that element.
In a neutral atom the number of electrons is equal to the number of protons. The opposite charge between protons and electrons is what allows for a neutral atom.
The number of electrons should equal the number of protons, otherwise you have an ion.
...the number of electrons. This balance between positive protons and negative electrons gives the atom a neutral charge overall.
The number of electrons should = the number of protons.
No, there is no requirement that the number of protons equal the number of neutrons. In fact, this gives rise to the various isotopes of a given element (Different isotopes will have different numbers of neutrons, while sharing the same number of protons). The number of protons is what generally defines an element. By being "uncharged" the atom is understood to have the same number of electrons as protons. Neutrons, being neutral, do not carry charge.
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.
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.
