What's the difference between an iconic bond and a covalent bond?

a. an iconic bond is a bond between charged atoms, while a covalent bond is a bond between neutral atoms

b. an covalent bond is a bond between charged atoms, while an ionic bond is a bond between neutral atoms

c. an ionic bond shares electrons, while a covalent bond is an attraction between opposite charges

d. an ionic bond is a bond between charged atoms, while a covalent bond is a bond between opposite charges

The correct answer is A an ionic bond is a bond between charged atoms,while a covalent bond is a bond between neutral atoms.

Explanation:

Ionic bond is formed between two atom that have huge difference in their electronegativity.The one atom loses electron thus becomes positively charged another atom receives that electron thus becomes negatively charged.

      For example NaCl

Covalent bond is formed by the sharing and paring of electrons.

    For example H2O

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
