How many valence electrons does carbon want?
every element wants to fill the outer shell. That means if it is at 5 electrons it wants to get to 8. If it is at 3, it wants to get to 0.
What is the purpose of elements to lose or gain valence electrons to become an ion?
they want to become stable by having all of the valence filled they want to become stable by having all of the valence filled
What is the valency number of magnesium?
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
What happens when with the valence electrons in an ionic bond?
let's use the ions Cl- and H+ forming HCl, hydrochloric acid, chlorine has 7 valence electrons and hydrogen has one, so when they form an ionic bond the valence shell is filled with 8 electrons. i hope that answered your question, I'm a chem major in college so i should know this stuff in and out but only a freshman so i don't lol ~Mau
How with 5 valence electrons will achieve a full set of valence electrons?
If you're asking how will an atom with 5 valence electrons will achieve a full set of valence electrons, then the answer would be that they bond with other atoms to gain a full set of the valence electrons by sharing or gaining 3 electrons.
How many electrons does an atom want in its valence shell?
8
How many valence electrons does bromine wants?
Bromine want an electron.
What are atoms valence electrons?
the electrons on their outer shell, all atoms want to gain a full valence shell.
How many valence electrons are in TiO2?
The electronic configuration of Tin is [Kr]4d10 5s2p2. Valence electrons are the electrons on the outermost shell of the neutral atom. Since the outermost shell is the 5th one, we have 4 valence electrons (2 of s and 2 of p)
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
How many electrons does Fluorine want to accept to reach a noble gas configuration?
Fluorine has 7 valence electrons and should gain 1 more electron.
How many valence electrons does carbon want?
every element wants to fill the outer shell. That means if it is at 5 electrons it wants to get to 8. If it is at 3, it wants to get to 0.
How many valence electrons do stable atoms have?
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
What is the purpose of elements to lose or gain valence electrons to become an ion?
they want to become stable by having all of the valence filled they want to become stable by having all of the valence filled
