1

Acidic Anhydride

Nonmetallic oxide that reacts with water to form an acidic solution

2

Acid Salt

Salt formed by replacing part of the H+ ions in a polyprotic acid with metallic ions. (Ex. NaHSO4)

3

Actinide Series

Series of radioactive elements starting with Ac and ending with Lr

4

Activated Charcoal

Type of carbon that has high degree of ADSORPTION

5

Adsorption

Adhesion (in very thin layer) of molecules of gases/dissolved substances/liquids to the surfaces of solid or liquid bodies that they come into contact with

6

Allotropic Forms

Forms of same element with different crystal structures

7

Alpha Particle

Positively charged (+2) helium nucleus

8

Amine

Compound derived from ammonia by subbing 1+ hydrocarbon radicals for H atoms (Ex. CH3NH2)

9

Acid turns litmus paper _____

Pink or red (Litmus paper is turned pink or red by ____)

10

Amorphous

Having no definite crystal structure

11

Amphoteric

A hydroxide that can have both acidic and basic properties (depending on which substance it reacts with)

12

Amide

Positively charged electrode Attracts negative ions Oxidation happens here

13

Antichlor

Substance used to remove excess Cl in bleaching process

14

Aufbau Principle

The principle that posits that: an electron occupies the lowest energy orbital that can receive it.

15

Bases turn litmus paper _____. They also _______ (accept/donate) protons.

This turns litmus paper BLUE and accepts protons.

16

Basic Anhydride

Metallic oxide that forms a base in water

17

Beta Particles

High-speed, negatively charged electrons 0-1e or -10ß emitted in radiation.

18

Binary

Compound composed of two elements

19

Boiling Point

Temperature at which vapor pressure of liquid equals atmospheric pressure

20

Breeder Reactor

Nuclear reactor where more fissionable material is produced than is used up during operation

21

Brownian Movement

Continuous zigzagging movement of collodial particles in a dispersing medium when viewed through an ultramicroscope

22
What is a calorie?

Calorie

Amound of heat needed to raise one gram of water one degree celsius

23

Carbonated water

water with CO2

24

Cathode

Electrode that is negatively charged and attracts positive ions. This is where reduction occurs.

25

Cathode Rays

Streams of electrons given off by the cathode of a vacuum tube

26

Chain reaction

Reaction produced during muclear fission where neutrons from one reaction start another and then another, etc.

27
Colligative properties depend on what?

Colligative properties

Properties dependent on concentration and not the type of particles present in solutions

28

Colloids

Particles larger than those found in solution but smaller than in a suspension

29

Control Rod

Part of a nuclear reactor than controls the speed of the chain reaction by absorbing neutrons. (A rod of a certain metal like cadmium)

30

Coordinate Covalence

Covalent bonding where both electrons in a pair come from same atom
