Most Atoms are more stable when they have eight valence electrons. The more electrons, the more stable. So No, most atoms are MORE stable when they have eight valence electrons.
Any element reacts only to achieve a stable state.This stable state is of having completely filled shells. So, an element having 8 valence electrons has its outermost or valence shell completely filled. So, it tends to react less.
Each atom has electron shells. If we think about "n"th electron shell, it can accommodate 2n2 electrons. If it has such number of atoms then it's in a more stable state.
In Other words, the first shell can accommodate 2 electrons, the second shell 8 electrons, the third shell 18 electrons, etc. The factor of two arises because the allowed states are doubled due to electron spin-each atomic orbital admits up to two otherwise identical electrons with opposite spin, one with a spin +1/2 (usually noted by an up-arrow) and one with a spin -1/2 (with a down-arrow).

no having eight valence electrons does not make elements more reactive, it actually makes it were they don't react at all because they have a full outer shell which make them not bond/react with other elements.
atoms don't have valence electrons only elements do from Periodic Table. Atoms are made of elements.
The octet rule states that the central atom has to gain 8 electrons in its valence shell to be bonded in a stable manner.
However, when there are available d-orbitals in the central atom, this would not necessarily be true.
Yeah...and by any chance, are you looking for answers to the Prentice Hall Physical Science workbook questions?
False. Its most stable when they have 8 valence electrons.
Yep. Atoms love to have 8 electrons in their outer energy level. The noble gases already do, and they don't react with anything for this reason.
Yes, it is true.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
There are eight electrons in the outermost energy level of a chloride ion.
One of these choices are your ansewr: * Octave * Balance * Valance * Octet
Oxygen (O) has 8 protons and 8 electrons.
Because it has it has eight electrons in the outermost occupied energy level.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Nobel gases are relatively nonreactive because they have eight electrons in the outermost energy level, which is a stable configuration

It forms an octet / stable electronic configuration
Oxygen (O) has 8 protons and 8 electrons.
The chloride ion has eight valence electrons.
Because it has it has eight electrons in the outermost occupied energy level.
If you're looking for a single word, my choice would be stable.Another term that could work if it's a neutral atom would be noble gas.
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
they become stable as they have completely filled outermost valence shell and if they have no electron in their outermost shell they become non reactive.
