Unit 2 Gen Chem 1 Review

Taken from the Prof Jones Notes only lol

Molecules

Matter made up of particles called atoms

Element

Type of matter composed of one kind of atom with each having one idenitial properties

Atoms

Small particles that retain their identity in chemical reactions

Compound

Contains atoms from 1 or 2 elements in fixed porpotions

Law of defitinity porportions

elements in fixed ratio to one another based on mass in a compound.

Nucleus

The center of the atom that contains protons and neutrons.

Electrons

The outer sphere of the atomic structure

What’s the charge of the electrons

Negative

Charge of Protons?

Positive

Charge of Neutrons?

Neutural charge

Nuclide

Atom characteized by definite atomic # and mass #

Atomic number

number that identifies specific elemtns and number of protons in nucles of atom

atomic structure

Isotropes

Atoms of some elements but different # of neutrons in nucleus

Atomic atomic mass (amu)

weighed mass of all naturally occuring isotrope

Peroid

Horitontal row, theres 7 of them

Group

Vertical column, theres 18 of them

Allotropes

Forms of the same element that differ in their phyiscal and chemical properties

ionic

metal +non metals

Molecular

2 or more nonmetals

Aqueous

Dissolved in water

Binary

Contains 2 elements

Ternary

Contains 3 or more elements

Acid

Contains hydrogen # one non metal

Oxyacid

Contains hydrogen, a non metal , & oxygen

Cation

Postivitvely charged ion, loses electons

Anion

negatively charged ion

Monoatomic

Charged particle from a single atom

Polyatomic

Charged particle of 2 or more atoms

Chemical formula

notation using atomic symbols w/ subscripts to convey relative porportions of elements

Hydrates

compounds containing a specific amount of water chemically bound

Group1 (minus H)

Alkiali metals

Group 2

Alkiline metals

Group 3-12 (minus La & Ac)

Transition metals

Group 13-16 (Yellow Part)

Metalloids

Group 14-16 w/ H (White Part)

Non metals

Group 17

Halogens

Group 18

Noble Gases
