Question

Organize Information Copy and fill in the graphic organizer below to describe one or more details for each concept: electron energy, valence electrons, stable atoms.

Concept:
a) Electron energy
b) Valence electrons
c) Stable atoms
d) None of these

Answer 1

Electron energy refers to the amount of energy possessed by an electron. Valence electrons are located in the outermost energy level of an atom and determine its reactivity. Stable atoms have completely filled energy levels and valence shells.

Step-by-step explanation:

Electron Energy: Electron energy refers to the amount of energy that an electron possesses. Electrons in an atom exist in different energy levels or orbitals, with the lowest energy level being closest to the nucleus. As electrons move to higher energy levels, they gain more energy.

Valence Electrons: Valence electrons are the electrons located in the outermost energy level of an atom. These electrons are involved in chemical bonding and determine the atom's reactivity. The number of valence electrons typically corresponds to the group number of the element on the periodic table.

Stable Atoms: Stable atoms have completely filled energy levels and valence shells. In other words, they have achieved a stable electron configuration. Noble gases are examples of stable atoms because their valence shells are completely filled, making them non-reactive.
