Unit 1: Biochem - chemical bonds

Question 1

why do atoms bond

Answer 1

stability
- full electron shells (8 or 2)

Question 2

nonpolar covalent bonds

Answer 2

• bond between elements in which electrons are equally shared
• this is a strong and stable bond

Question 3

polar covalent bonds

Answer 3

• bond between elements in which electrons are not shared equally (more towards the more electronegative element)
• strong and stable

Question 4

electronegativity

Answer 4

elements level of attraction of electrons

Question 5

hydrogen bonds

Answer 5

• bond between molecules based on the attraction between a positive and negative charge
• weak bond

Question 6

why does shape matter

Answer 6

bonds between elements create their shapes and the shape then determines their function
