Chapter 1.1 The study of chemistry

Question 1

CHEMISTRY

Answer 1

Is the study of matter and the changes that matter undergoes

It is the study of the properties and behavior of matter

It seeks to understand the properties and behavior of matter by studying the properties and behavior of atoms and molecules

Question 2

MATTER

Answer 2

Is the physical material of the universe

It is anything that has mass and takes up space

Question 3

MASS

Answer 3

is a measure of the amount of material in an object

Question 4

PROPERTY

Answer 4

any characteristic that allows us to recognize a particular type of matter and distinguish it from other types

It relates to bothe the composition and the struture of matter

Question 5

Why are there so many varieties of Matter

Answer 5

Because of the the different combinations of ELEMENTS

Question 6

ELEMENTS

Answer 6

A PURE SUBSTANCE

A substance consisting of atoms of the same atomic number.

A substance that cannot be seperated into simplier substances

Question 7

ATOMS

Answer 7

The smallest part of a pure substance(an element).

The infinitisimally small building blocks of matter

Each element has a unique kind of element

Question 8

a Matter’s **COMPOSITION **refers to

Answer 8

The particular elements/atoms it contains

Question 9

A matter’s STRUCTURE refers

Answer 9

The arrangements of the atoms it contains

Question 10

MOLECULE

Answer 10

2 or more of the atoms joined together in a specific shape

Question 11

The Hiearchy of Matter

Answer 11

Matter->-(different combinations of) Elements–> Molecule–>Atoms

Question 12

Minor changes in composition or structure of atoms in results in what

Answer 12

Changes in its property

Question 13

3 things that chemists do

Answer 13

1. make new types of matter: materials, substances, or combinations of substances with disered properties
2. measure the properties of matter
3. develop models that explain and/or predict the properties of matter
