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)
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
No, they arent. Valence electrons are the amount of electrons the element has in its outermost shell. Electrons dont bond, they can either be shared or transferred. An ionic bond transfers electrons and a covalent bond shares 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.'
Periods in the periodic table tell you the number of electron shells an element has. As you move across a period from left to right, the number of protons, electrons, and valence electrons increases by one, resulting in elements with similar chemical properties being grouped together.
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.
Yes, but valence electrons are always in the outer electron shell of an atom.
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
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.
There are 2 valence electrons in Barium.
Oh, dude, that's like asking me to remember my high school chemistry class! The element you're looking for is aluminum. It's got 2 electron shells and 3 valence electrons hanging out, doing their thing. So yeah, aluminum is your guy for that question.
No, they arent. Valence electrons are the amount of electrons the element has in its outermost shell. Electrons dont bond, they can either be shared or transferred. An ionic bond transfers electrons and a covalent bond shares electrons.
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
noble gases, or inert gases they are the same thing and they are group 18 they have full valence electrons so they are unlikely to react with other elements
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.
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.
You can determine the valence electrons in a element by its group number. Like in group 1 those elements in group 1 have only 1 valence electron. group 2 same thing, but we skip the other groups and go straight to group 13. Group 13 would 3 valence electrons same with 14= 4 ,15= 5 ,16= 6 ,17= 7 ,18=8. So the answer to your question is Flerovium has 4 valance electrons since it is in group 14.
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.
