Bonding:Intramolecular (slides #1-30)

Question 1

intramolecular

Answer 1

within the molecule (the bonds between atoms)

Question 2

chemical bonds

Answer 2

• attractive force between atoms or ions
• chemical changes are due to changes in bonds.
• in an atom, the protons in the nucleus and the electrons are held together by attractive forces.

Question 3

chemical bonds are caused by

Answer 3

the attraction of one atom’s nucleus to another atom/ion’s electrons.

Question 4

its can only be a molecule

Answer 4

if it is covalently bonded, nonmetals only.

Question 5

potential energy

Answer 5

stored in the bonds between atoms or ions.

Question 6

chemical energy

Answer 6

energy involved in making and breaking of bonds

Question 7

energy changes in bonding

Answer 7

• when 2 atoms are bonded to each other they are at a LOWER and more stable potential energy level if it is a STABLE bond
• unstable bonds will have higher potential energy than the original atoms

Question 8

when strong bonds form, it is an _________ reaction, and the products have _____potential energy

Answer 8

exothermic reaction, less
