Homework Answers
1. two atoms are isotopes means , they have same number of protons or the atomic number is same but the number of nutrons are different in the nucleus or the atomic weight is different .
2. Covalent bond is a type of chemical bond where two or more atoms share there one or more electron pairs for forming a stable , strong bond called as covalent bond.
3.
| POLAR CPVALENT | NONPOLAR COVALENT |
| they formes between two atoms which have little differece in electronegativity | they formes between two atoms which have simmilarity in electronegativity |
| electrons are shared unequaly between two atoms | electrons are shared equaly between two atoms |
| dissolve in water | do not dissolve in water |
| polar bonds have dipole movement | nonpolar bonds have no dipole movement |
4. hydrophobic means water phobia or water fearing. The hydrophobic molecle does not attract water , they repel water . They does not dissolved in water.
5. pH measure the acidic and basic charecters of substances , like water , blood , digestive juice etc. It measures between the range of 0 to 14. where less than 7 indicate more acidic and greater than 7 indicate more basic.
6.
| Kinetic energy | Potential energy |
| this type of energy present in the body due to the property of motions | this type of energy present in the body due to the property of state |
| this is transferable from one body to another | this is not transferable from one body to another |

COOH- carbixylic group.
NH2- amino group
OH - hydroxyl group
PO4-2- phosphate group
