29
New cards
Element
 A pure substance that cannot be broken down into other substances by chemical means
30
New cards
Molecule
 Two or more atoms of the same element bond together
31
New cards
Compound
 A substance made up of two or more different elements that have been chemically joined
32
New cards
Ex
CH4 (Carbon and 4 hydrogen atoms; since there are more than 2 atoms of the same element, its a molecule; but its also a compound because its composed of two different types of elements)
33
New cards
Covalent Bonds
 When two atoms share one or more pairs of electrons
34
New cards
Ionic Bonds
 When atoms are held together by the attraction between opposite charges
35
New cards
Explanation
Sodium has one valence electron, which is why it tends to give that up, causing it to gain 1 positive charge
36
New cards
Hydrogen Bonds
Attraction between a hydrogen atom with a positive charge and negative charge
37
New cards
Ex
water molecules are polar because oxygen has a negative charge and hydrogen has a positive charge
38
New cards
Polarity
A molecule in which the charges are unevenly distributed (partial positive and negative)
39
New cards
Ans
Water molecules have an uneven distribution of electrons, with the oxygen atom having a negative charge and the hydrogen atoms having a positive charge
40
New cards
