The number of protons equals the number of electrons in an uncharged atom.
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.
No - in fact it is quite rare
In a neutral atom, the number of protons is always equal to the number of electrons.
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.
The number of electrons should = the number of protons.
An atom is neutral when the number of protons in the nucleus is equal to the number of electrons surrounding the nucleus. Protons are positively charged, while electrons are negatively charged. The opposite charges balance each other out, resulting in a neutral overall charge for the atom.
For a neutral atom, the number of protons is equal to 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.
An equal number of protons and 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.
The protons and electrons are equal in number in a neutral atom
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.
