Carbon has 6.
NaCl - Na+ has 10 electrons and Cl- has 18 electrons
This describes an ionic compound with an 8:3 ratio of electrons to cations. The cation has a charge of +3, meaning it has lost 3 electrons. The total number of electrons in the compound is 80.
When an atom or ion has 8 valence electrons, it is generally more stable, as it fulfills the octet rule. This stability is due to achieving a full outer electron shell, which is energetically favorable. Atoms or ions with fewer than 8 valence electrons may be more reactive, as they tend to gain or lose electrons to achieve a full octet.
Generally, 8 or less electrons may only inhabit the second ring.
The central atom B has less than 8 electrons in the valence shell. BF3 has a tendency to accept electron pair.
They have less slightly less than 8 valiance electrons.
NaCl - Na+ has 10 electrons and Cl- has 18 electrons
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
The element in question is magnesium. It has 12 protons (more than sodium and less than argon), 2 more valence electrons than oxygen (which has 6), and 8 fewer valence electrons than neon (which has a full valence shell with 8 electrons).
Any element except the elements in group 8, 9, 10, 11, 12 and 18 have lesser than 8 valence electrons.
All of them. Except the noble gases.
-8 is less than 8
This describes an ionic compound with an 8:3 ratio of electrons to cations. The cation has a charge of +3, meaning it has lost 3 electrons. The total number of electrons in the compound is 80.
-8 is less than all positive numbers, including 8. -8 is 8 less than 0, and 0 is eight less than 8.
When an atom or ion has 8 valence electrons, it is generally more stable, as it fulfills the octet rule. This stability is due to achieving a full outer electron shell, which is energetically favorable.

-8 < 8 Think of a thermometer scale. -10 degrees is colder than (+)10 degrees
