Question 3

Cation

Answer 3

Positive ion that is formed by an atom losing one or more electrons

Question 4

Anion

Answer 4

Negative ion that is formed by an atom gaining one or more electrons

Question 5

Chemical bond

Answer 5

Interaction between two or more of the same or different atoms that results in forming molecules

Question 6

Electronegativity

Answer 6

Ability of some elements to attract electrons (often of hydrogen atoms) acquiring partial negative charges in molecules and creating partial positive charges

Question 7

Hydrogen bond

Answer 7

Weak bond between slightly positively charged hydrogen atoms and slightly negatively charged atoms in other molecules

Question 8

Polar covalent bond

Answer 8

Type of covalent bond that forms as a result of unequal electron sharing resulting in creating slightly positive and negative charged molecule regions

Question 9

Van der waals interaction

Answer 9

Very weak interaction between molecules do to temporary charges attracting atoms that are very close together
