There is no such term used in science. However, in psychology the term refers to non-verbal communication received in a positive manner (a smile is a good example).
A negative valence is when an atom gains electrons (typically to satisfy the octets law).
there are 3 valence electrons in the atom of aluminum
It has a negative charge which means its -2 :) Hope this answers the question!
An element that has one valence electron tends to be more reactive, is able to form ions, and can become charged When an element has all eight valence electrons, they are more stable.
Positive 1 charge
Yes, but only if its positive. If its negative, it shows the number of electrons need to become stable.
its a valence number which is and above
Yea.
Yes, they do.
the electrons in the outermost shell of an atom are considered to be the valence electrons.
it becomes positive
I am not positive what you mean by "core electrons" but: 57 (total) 7 (valence, outermost) 50 (non-valence, everyone but valence)
valency of carbon is positive as it gives it electron so it is positively charge
positive (+ is always positive) This means it's an ion, because it's lacking one valence electron
The noun 'valance' is a word for a length of decorative drapery attached to the canopy of a bed or hung above a window to conceal hardware.Example sentence:We have enough extra fabric to make a valance to match the drapes.
Positive ions are called cations. Negative ions are called anions.
there are 3 valence electrons in the atom of aluminum
Do you know what valence is? Seems not. It is the overall electric charge on an ion. Opal is silica, or silicon dioxide= SiO2. There is no valence associated with any stable compound. Perhaps you want the valence of the Silicon ion--that would be 4 positive, since Oxygen is 2 negative.
