Chemical bonds tend to occur so that an atom gets a "full" valence shell. Two main types of bonds are ionic and covalent. What is the main way these two types of bonds differ?

The two bonds differ mainly in the number of electrons shared. In covalent bonding, sharing always happens

in pairs, whereas in ionic bonding, single electrons can be shared.

The two bonds differ mainly in the whether whole or partial electrons are shared. In covalent

bonding, whole sharing always happens, whereas in ionic bonding, partial electrons can be shared.

In covalent bonding the two (or more) atoms bonded together share electrons. In ionic bonding, one atom

loses one (or more) electrons, while another atoms gains one (or more) electrons.

Explanation:

Atoms of molecules and elements come together chemically. The atoms of the same or different elements are joined together by means of chemical bonds, which are of different types depending on how it is formed. These chemical bonds include; covalent bonds, ionic bonds, hydrogen bonds etc.

- Covalent bonding occurs between atoms in such a way that the two or nore atoms involved share their valence electrons. Examples are CO, H2O etc

- On the contrary, ionic bonding also called electrovalent bond, is that type of bonding in which one atom transfers electrons to the other atom. Hence, the atom that loses electrons becomes more electropositive while the atom that accepts electrons become more electronegative. Examples are MgO, CaCl2 etc

hello which   of the following there is nothing!

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
