Carbon atoms always have how many covalent bonds?A) oneB) twoC) threeD) fourE) five

Carbon (from Latin: carbo “coal”) is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds .It belongs to group 14 of the periodic table. Carbon makes up only about 0.025 percent of Earth’s crust. Three …

Octet rule – Wikipedia

Pauling proposed that this molecule actually contains two three -electron bonds and one normal covalent ( two -electron) bond . The octet on each atom then consists of two electrons from each three -electron bond plus the two electrons of the covalent bond plus one lone pair of non-bonding electrons. The bond order is 1+0.5+0.5=2.

In chemistry a single bond is a chemical bond between two atoms involving two valence electrons.That is the atoms share one pair of electrons where the bond forms. Therefore a single bond is a type of covalent bond .When shared each of the two electrons involved is no longer in the sole possession of the orbital in which it originated. Rather both of the two electrons spend time in either …

Other carbon compounds and other molecules may be explained in a similar way. For example ethene (C 2 H 4) has a double bond between the carbons. For this molecule carbon sp 2 hybridises because one π (pi) bond is required for the double bond between the carbons and only three σ bonds are formed per carbon atom. In sp 2 hybridisation the 2s orbital is mixed with only two of the three …

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms .These electron pairs are known as shared pairs or bonding pairs and the stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalen…
