# What does it mean when carbon has 4 valance electrons?

It means that there are 4 electrons on its outer most ring, but only neutral atoms have valence electrons. Since carbon has 4 valence electrons it either needs to lose 4 electrons or gain 4 electrons to form an octet which makes it stable.

On the periodic table there are groups, 1A-8A. The nuber tells you how many valance electrons the elements have. Carbon is in group 4A, so it has 4 valance electrons.

Take carbon as an example.Carbon, indicated by it's atomic number, has 6 electrons. The number at the top of carbon's group is the number of valance electrons. Carbon has 4 valance elections.6 total electrons - 4 valance electrons= 2 core electrons in carbon=====================(try another element yourself to see this process )

Carbon = 4 valance electrons. Oxygen = 6 valance electrons. Chlorine = 7 valance electrons. Sodium = 1 valance electron Magnesium = 2 valance electrons. Neon = 8 valance electrons. I am reading this at the top of my periodic table where every group of elements has it's valance number listed.

Since carbon has 4 valance electrons, if it shares all 4, it then has a full outer shell of 8 electrons, which is a stable configuration, in accordance with the octet rule.

By looking at the group number you can tell how many valance electrons there are ex: Group 1= 1 valance electrons Group 2-12= 2 valance electrons Group 13= 3 valance electrons Group 14= 4 valance electrons Group 15= 5 valance electrons Group 16= 6 valance electrons Group 17= 7 valance electrons Group 18= 8 valance electrons

Carbon = 4 valance electronsNitrogen = 5 valance electrons4 + 5 = 9 and 2 valance electrons used for the single bond, 9 - 2 = 73 hydrogens can attach to the carbon and 4 hydrogens can attach to the nitrogen, so.......7 hydrogen atoms would complete this molecule===================================

== == == == Carbon have 4 valance electron and oxygen have 6 electrons so Actual electrons = 4+60=10 Needed = 16 so they share 6 electrons and 3 pairs, so tripple. triple bond

AnswerCarbon have 4 valance electron and oxygen have 6 electronsso Actual electrons = 4+60=10Needed = 16so they share 6 electrons and 3 pairs, so tripple.triple bond

Look at the valance number at the top of every family of elements. For example; looking at column 4A, the carbon family, I see 4 valance electrons signified. This means that 4 electrons are needed to fill the outer shell to the octet state. So I know that carbon can form 4 covalent bonds.

There are 4 valence electrons in the element Tin.

Read the numbers at the top of the columns. 1A = 1 valance electron of the alkali metals. 4A = 4 valance electrons of the carbon family. Remember, transition metals have varying oxidation states. The can donate various numbers of electrons though the top numbers generally give an accurate valance number.

A carbon atom has 4 valence electrons. I am not sure what you mean by C2; do you mean two carbon atoms? If so, they have 8 valence electrons between them.

The family containing 7 valance electrons is called the Halogens. They are all called (in order of increasing valance electrons): Alkali Metals(1), Alkaline Earth Metals(2), Boron Group(3), Carbon Group(4), Nitrogen Group(5), Oxygen Group/Chalcogens(6), Halogens(7), and Noble Gasses(8/full).

XeF4 Xe has 8 valance electrons. F has 7 valance electrons * 4 = 28 valance electrons 8 + 28 = 36 valance electron total. Now, there are 4 bonds between Xe and the 4 F's, so that is a total of 8 electrons shared. 36 - 8 = 28 valance electrons left over. That means that 6 each go around the fluorine atoms as three lone pair per atom and one electron for the exon atom, unless this is a charged molecule.

The charge of Carbon is +4 or -4 .... it can gain 4 electrons or loose 4 electrons.

2H = 2 valance electrons.S = 6 valance electr4ons----------------------------------------add8 valance electrons altogether and subtract 4 for the two sigma bonds. 4 electrons left, two lone pair.H-S-H------------put two electrons above the S and two electrons below the S. :, like that, only horizontal.
