In most cases ionic bond takes place between metal and non metals like NaCl and MgO but in some reactions covalent bond is also formed like BeCl2

Ionic bonding takes place between ions. So, it can be said that it has most amount of ionic character
metalloids are the seven elements on the "staircase"(bold line located in the middle of the table) they are B, Si, Ge, As, Sb, Te, At. all metals are found on the left side of the "staircase" all non metals are found on the right side of the "staircase" exception to the rule: hydrogen, it is a non metal
it is a type of bonding which take place between atoms in a compound ;in which one atom has lone pair of electron and other has vacant orbital placed adjacent to each other. A compound which posses back bonding has pi bonding character because it occurs after formation of sigma bond. Usually ; back bonding causes molecule to get stable as it completes octet. for ex. in borontriflouride , back bonding causes decrease in bond length and increase in bond order.
what is chemical bonding
Ionic bonds form between a metal and a non-metal and involve a share of electrons. Metals have positive charges and non-metals have negative charges (based on their valence electrons) so they are ions. i.e. Magnesium Chloride: Mg2+ + Cl- ----> MgCl2
In metals there is metallic bonding, in which all the metal atoms contribute valence electrons to a commonly shared electron cloud.
Well, non metals are a gas at room temperature and so, they were never really a solid in the first place.
Covalent... Ionic bonds take place only between metals and non-metals whereas covalent bonds occur between non-metals only. Since Carbon, Hydrogen and Oxygen are non-metals, the type of bonding occurring here is covalent
no reaction takes place
An ionic bond
when two type of non metals bond together , they always bonded by covalent bond because they have the tendency to share the electrons as all the non metals are electronegative so the process of losing and gaining cannot take place ...because in two non metals no one can lose electron so they have to share electons for example in water(H2O, CO2 etc...)
No, NaCl is an ionic salt. Since, chlorine is highly electronegative and sodium is highly electropositive therefore, the bonding between them takes place by ionic bond.

Because in order for a subsance to undergo reduction and become an oxidizing agent, the substance must gain electrons. Non metals therefore gain electrons while they are in their pure form while metals loose electrons in their pure form. Examples include: non metals- Cl2 + 2e- -> 2Cl- Br2 + 2e- -> 2 Br- Metals- Sn -> Sn2+ + 2e- Ni -> Ni2+ + 2e-
Allotropy can take place in any phase. For example, O2 and O3 are two different allotropes of oxygen. They are both typically gaseous at room temperature
