An Atom Is Electrically Neutral

Posted on  by admin
  • (b) In an atom, the number of protons in the nucleus is the equal to the number of electrons in the extra nuclear portion. Since each proton and each electron has the same charge but with opposite magnitude, atom is therefore, electrically neutral. (c) The atoms of the noble gas elements have complete outermost electron shells.
  • To better understand unstable atoms, it helps to appreciate what constitutes stability. In the familiar planetary model, an atom consists of a nucleus of heavy positively charged particles, called protons, and electrically neutral ones called neutrons. Orbiting the nucleus is a cloud of lighter, negatively charged electrons.
  • An atom contains sub atomic particles electrons, protons and neutrons. Electrons are present in the outer shells. The given atom contains eleven electrons. The atom is neutral so the number of electrons will be equal to number of protons.
  • An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.

Yes atom is electrically neutral. It consist up of 3 main subatomic particle: Electron (negatively charge) Proton (positively charge).

An Atom Is Electrically Neutral When


Base your answers to questions 54 and 55 on the information below.

An atom in an excited state has an electron configuration of 2-7-2.

54 Explain, in terms of subatomic particles, why this excited atom is electrically neutral. [1]


NOTE='Atoms' are neutral

The number of protons equals the number of electrons.

The atom has 11 protons and 11 electrons.

55 Write the electron configuration of this atom in the ground state. [1]
