Each carbon atom has 4 . In acetylene, there are 3 carbon-carbon bonds, i.e. 6 electrons shared between the carbons. And in ethylene there are 4 electrons shared between the carbon atoms; the remaining 2 electrons constitute half of the $C-H$ bonds.
The relative of carbon is 12.011, which is extremely close to 12.0. This means that the masses C-13, and C-14 are practically negligible when contributing to the relative atomic mass...
This is called the of the element. To make it up to 13 in carbon-13, you will need 7 neutrons. Stable isotopes are not useful at all in radio-dating,...
Carbon atoms have four electrons in their outer shell. So, it exhibits tetravalency & thus, a single carbon atom can form a maximum of four (4) bonds with other atoms....
Each nitrogen atom has 5 . When two nitrogen atoms bind to form the dinitrogen molecule, each atom provides 3 electrons to give the treble bond, and the remaining pair...
A chlorine atom has 7 electrons in its outer shell. If it shares one of those with another chlorine atom (and the other one with the first), they can both...
When electrons are unequally shared, it is a polar-covalent bond, and when one atom gets the electron exclusively the two charged ions form an ionic bond.
Take ethylene $H_2C=CH_2$; around each carbon atom there are 4 . Two of these electrons combine with 2 hydrogen atoms (each with 1 electron) to form $2xxC-H$ bonds. Each carbon...
Consider the ethane molecule, $H_3C-CH_3$. Each carbon atom has 6 electrons, 2 of which are inner core and are along for the ride. Thus, there are 4 electrons in the...
There are 4 orbitals, 4 bonding electron pairs, around the central carbon in $"carbon tet"$. The bonding orbitals are arranged in a tetrahedron to give a molecule with tetrahedral geometry....
