Alkanes represent one family of organic compounds that is composed of carbon and hydrogen.
Alkanes are organic compounds that solely have hydrogen and carbon atoms in single bonds and do not have any additional functional groups. Alkanes can be divided into three groups: cycloalkanes, branched alkanes, and linear straight-chain alkanes.
The general formula for alkanes is CnH2n+2. Alkanes are also saturable hydrocarbons. Cyclic hydrocarbons like cycloalkanes have rings-shaped arrangements of their carbon atoms.
Therefore, Alkanes are an example of an organic chemical family made of carbon and hydrogen.

Using electronegativity difference is a good guide to the ionic/ covalent nature. Large differences indicate greater ionic character, small differences more covalent character. The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have.
Ionic bonding is formed through electrostatic attraction between a cation and anion. Foe example, Sodium fluoride has ionic bonding because it is composed by sodium and Fluorine (a non metal). On the other hand, covalent bonding is characterized by atoms sharing pairs of electrons. For example; methane has covalent bonding; carbon has 4 valence electrons and hydrogen has 1; when they bond they have a total of 8 electrons and satisfies the octet rule.
Go get a science teacher but i think it is because ................
For that you have to use the Aufbau principle
For example, writing the electronic configuration of Fe(28)
I recommend that you memorize the aufbau principle. Once you learn it, you don’t need anything else except the atomic number of the element to write it’s electronic configuration.
