What conditions result in a stable electron configuration?
Formation. Ionic bonding can result from a redox reaction when atoms of an element (usually metal), whose ionization energy is low, give some of their electrons to achieve a stable electron configuration.
What makes atoms have a stable electron configuration?
Atoms are stable when they have eight valence electrons (two in the case of hydrogen). This is called having an octet. Only the noble gases have an octet of valence electrons naturally (two for helium, which is called a duet). The valence electrons are in the outermost energy shell.
Which configuration is considered stable?
Stable configuration Noble gases have stable configurations. Their valence shell is complete. They have two or eight electrons in their valence shell. They do not gain, lose or share electrons.
What is a stable electron configuration?
Electron configurations can also predict stability. An atom is at its most stable (and therefore unreactive) when all its orbitals are full. The most stable configurations are the ones that have full energy levels. These configurations occur in the noble gases.
Answer and explanation: Electron configuration is the distribution of electrons in an atom. In order for the electron configuration to be stable, an atom (o ther than Hydrogen and Helium) must have a full outer octet, or 8 electrons in it’s outermost shell .
What electron configuration do the noble gases have in common?
Noble gases have eight valence electrons, that is, they have eight electrons in their outermost orbit (except helium). Thus, they exhibit stable octet or duplet configuration. Hence, the elements of group 18 exhibit very high ionization enthalpies.
Which electron configuration represents a transition element?
The general electronic configuration of transition elements is (n-1)d 1-10ns 1-2. The (n-1) stands for inner shell and the d-orbitals may have one to ten electrons and the s-orbital of the outermost shell (n) may have one or two electrons.
Does lithium have a stable electron configuration?
A lithium atom has two electrons orbiting in an inner shell and only one electron orbiting in its outer shell. The outer shell is incomplete, and therefore unstable. Li atoms readily give up one electron to form positively charged, Li+ ions. These ions have the same stable electron configuration as the noble gas helium.
