What happens to an electron when energY is added to a atom?

Answer 1

Adding an electron to an atom can result in one of three things. It will depend on what condition the atom starts in. For an atom that has less electrons than protons (a positive ion), it will make that atom less positive. If the atom has just one less electron than the number of protons, the additional electron will neutralize that atom. In a neutral atom, the extra electron will make that atom a negative ion. In an atom with one or more electrons than protons, that atom will be a negative ion, and the additional electron will simply make it more negative. Also, when an electron is added to a neutral atom, energy is released

Answer 2

You cannot add energy to an electron, as it is pure energy. However, you can add electrons from another atom to the original atom (as long as the original atom has less than eight electrons in it's outermost energy level) to create a bond between the two atoms.

Answer 3

The energy can be absorbed by the electron, causing it to jump to a different energy level. Later it returnd to the "ground state" and releases the energy as a particular spectrum of e-m radiation (sometimes light). This is a test used sometimes to identify the element because different elements have diffeent spectra (colors) emitted.

Sometimes the energy causes the electron to be completely removed from the atom forming a positive ion. This is called ionization energy.

Answer 4

When energy is added to an atom, an electron can be excited to a higher energy level, moving to a higher orbital further from the nucleus. This temporary promotion of the electron is known as an excited state. The electron can later release this energy by emitting a photon and returning to its original energy level.

Answer 5

when energy is added to an electron, it gains negative charge

Answer 6

The electrons jump to a higher orbit or level

Answer 7

When energy is added to an atom, the electrons move to outer levels of the shell. When they drop back down, they release the energy in the form of photons.

Answer 8

If an atom receives another electron, it will become an isotope of the atom, and will gain a negative charge, since there will be more electrons that protons.

Answer 9

It becomes an anion.
