Answer to Question #224082 in Biology for Thandi

Question

Define the terms below:

(1) Hydrogen bond

(2) Inorganic compound

(3) Ionic bond

(4) Organic compound

(5) Periodic table

Answer 1

1) Hydrogen bonding, interaction involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons; such a bond is weaker than an ionic bond or covalent bond but stronger than van der Waals forces.

2) Inorganic compound, any substance in which two or more chemical elements (usually other than carbon) are combined, nearly always in definite proportions. Compounds of carbon are classified as organic when carbon is bound to hydrogen.

3) The ionic bond is the electrostatic force of attraction between a positively charged metal ion and a negatively charged non-metal ion. 

4) Organic compound, any of a large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen. 

5) Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number.
