Flashcards in Quest #3 Deck (15):
1

Metals
Period 1-16
1= 1+
2= 2+
Transitions charges vary in charges. Roman Numerals

Metalloids
Along the stair step 14-17
an element that has both metallic and nonmetallic properties

2

Compounds

elements which bond together to form compounds, substances have the same composition no matter where they are found

3

Chemical Formulas

a representation of a molecule in which the symbols for the elements are used to indicate the types of atoms present and subscripts are used to show the relative number of atoms.

4

Molecular Formula

The exact formula of a molecule, giving the types of atoms and the number of each type

5

Molecular Weight

he mass in grams of one mole of a substance

6

Molecular Compound

-made up of non-metals
-no charge
-crystal lattice structure-molecules stay in tact
-no free ions
-no electricity conducted

7

Ionic Compound

-metal plus a non-metal
-involves charges but neutral
-crystal lattice structure
-free ions in solution-electrolytes
-conducts electricity

8

Compounds in solution

Ionic- electrolytes- free ions -conduct electricity
Molecular- stays in tact- separated from other compounds but ions not broken. no charge- no electricity conducted

9

Ions

an atom or a group of atoms that has a net positive or negative charge

10

Poly-atomic Ions

An Ion containing multiple atoms

11

Nomenclature

Naming compounds---practice

12

Coulomb’s law

The magnitude of the electrostatic force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distance between them

13

Crystal Lattice

Crystals are composed of three-dimensional patterns. These patterns consist of atoms or groups of atoms in ordered and symmetrical arrangements which are repeated at regular intervals keeping the same orientation to one another.
Both ionic and molecular compounds have this structure. But molecular each compound is a whole.

14

Electrolytes

free ions in solution. conduct electricity -ionic compounds

15

Diatomic

are molecules composed of only two atoms, of either the same or different chemical elements
Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, Bromine
