Question

what are the two main types of chemical bonds

Answer 1

1. ionic bond- bond form by transfer of electrons. ex-NaCl
2. covalent bond- bond form by mutual sharing of electrons. ex-CH4

Answer 2

There are three types of bonds:-

1. Metallic bond= bond which exists between metal atoms. It is the sharing of many detached electrons between many positive ions.
2. Covallent bond= bond which exists between non-metal atoms. Non-metals share there electrons.
3. Ionic bond= bond which exists between metal and a non-metal. Metals donate electrons becoming positive ions and non-metals gain electrons becoming negative ions.
