Valency is the number of electrons in the outer shell
the charge is how many electrons is needed to form an octet (full valence = 8 electrons)
Eg. Sulfur
valence = 6
charge = -2 (needs to gain 2 electrons to gain an octet)

∙ 14y agoelectron shells are the actual rings around the nucleus. this number is shown on the Periodic Table by the row it is in. this number shows how many electron shells you have. valence electrons are the number of electrons in the outer electron shell.

∙ 13y agoNo, valence electrons the electrons which orbit around an atom in the furthest most electron shell. Ions are atom with either fewer or more electrons than its ground state.
For Example:
Element 15, Phosphorous, has 15 total electrons in its ground state, 5 of which are the valence electrons. P+, an ion of P, has lost an electron for a total of 14 electrons, 4 of which are valence electrons. P-, another ion of P, has 16 electrons, 6 of which are valence electrons.

Valence electrons are the elctrons that are furthest from the nucleus (outermost electrons).
Valence shell is the outer-most shell.
Valence electrons are located in the valence shell.

Are electron shells and electron dots the same thing?
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
What determines the electron-group geometry of a molecule?
Electronegativity of each atom is what determines the electron distribution of a bond. The electronegativity of an atom affects its distance in its valence electrons and its atomic number.
What is meant by reliance electrons?
No such thing. Did you mean valence electrons? Those are the outermost electrons in an atom, and they are the ones that are used in a chemical reaction.
Do all atoms have valence electrons?
It depends on the atom. An atom is made of 3 subatomic particles- a negatively charged electron, a positively charged proton, and a neutral neutron. If the number of electrons and the number of protons are different, then the atom has a net charge. If the number of electrons and the number of protons are the same, then the atom is said to be neutrally charged. Changing the number of neutrons affects the mass and therefore important traits of each atom, but does not affect its charge. Atoms that have a net charge are called 'ions.'
Is eight valence electrons is called an?
Eight valence electrons would complete the out shell. If the outer shell was complete it would still be called the same thing, however the charges would be different.
Is a valence electron the same thing as a electron?
Yes, but valence electrons are always in the outer electron shell of an atom.
In pi3 total of valence electron?
No such thing as pi3, but if you mean PI3, then there are 5 valence electron in P, and each I has 7 valence electrons for a total of 5 + 7 + 7 + 7 = 26 valence electrons.
Are electron shells and electron dots the same thing?
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
How many valence electrons does barium have?
There are 2 valence electrons in Barium.
What does a atom's outermost electron shell does?
The outer energy level is in the electron cloud surrounding the nucleus. Each ring that surrounds the nucleus is an energy level and contains a different number of electrons.
Why chloride and oxide form nagaive ions?
Chlorine atoms have 7 valence electrons and need only 1 more in order to become stable (having 8 valence electrons). It takes much less energy to add an electron to a chlorine atom than it does to remove 7 valence electrons, so the chlorine atom gains one electron and becomes a negative ion with a 1- charge. The same thing is true of oxygen, except that it has 6 valence electrons, so it will gain 2 electrons and becomes a negative ion with a 2- charge.
Why do you only sketch the valence electrons in the electron dot diagram?
valence electrons are the parts of an element that will attach to another element, but only if they reach a certain point. nothing else is a factor. the only other thing added is polarization, which affects how the shape of an atom will come out
How do electron move in atoms?
I'm not 100% sure but as far as i know, Electrons move in "shells" just research, Niels Bohr he figured the whole thing out.
How many valence electrons in calcium ion?
Type your answer here... The number of valence electrons in calcium is 20, because it's almost the same thing as it's atomic number.
What determines the electron-group geometry of a molecule?
Electronegativity of each atom is what determines the electron distribution of a bond. The electronegativity of an atom affects its distance in its valence electrons and its atomic number.
How many valence neutrons does helium have?
First of all there is no such thing a a valence neutron. However there are valence electrons.Valence electrons are the electrons of the outer most layer or shell called valence shell. Based on a Bohr diagram or Lewis structure you can see that Helium has 2 valence electrons.
What two thing surround every moving electron?
Shells and atoms
