Question 2

Mass

Answer 2

The amount of matter in an object

Question 3

Weight

Answer 3

Gravitational force acting on an object of a given mass

Question 4

Element

Answer 4

The simplest type of matter having unique chemical properties

Question 5

Atom

Answer 5

Is the smallest particle of an element that has the chemical characteristics of that element

Question 6

Neutron

Answer 6

Has no electrical charge

Question 7

Proton

Answer 7

Has one positive charge

Question 8

Electron

Answer 8

Has one negative charge

Question 9

Nucleus

Answer 9

Protons and neutrons form here this is at the center of an Atom

Question 10

Isotopes

Answer 10

Are two or more forms of the same element that have the same number of protons and electrons different number of neutrons

Same atomic number different atomic mass

Question 11

Atomic mass

Answer 11

The average mass of it’s naturally occurring isotopes

Question 12

Chemical bonds

Answer 12

First level is the concept of how atoms interact to form molecules by sharing in transferring their out most electrons

Question 13

Chemical behavior

Answer 13

An atom is dependent on its electrons

Question 14

Electron shells

Answer 14

Energy levels are often depicted as concentric rings around the nucleus

Question 15

Valance shell

Answer 15

Outer most shell

Question 16

Octet rule

Answer 16

Most atoms follow the tendency of Atoms to combine with other Atoms each has eight electrons and it’s a valance shell

Question 17

Two ways to achieve octet

Answer 17

The transfer of electrons between Atoms in the sharing of electrons between Atoms

Question 18

Electronegativity

Answer 18

Ability of an atoms nucleus to attract electrons

Question 19

Cations

Answer 19

Positively charged sodium ions

Question 20

Anions

Answer 20

Negatively charged ions

Question 21

Ionic bond

Answer 21

Electrons are transferred between atoms creating oppositely charged ions

Question 22

Covalent bond

Answer 22

When atoms share one or more pairs

Question 23

Single covalent bond

Answer 23

The sharing of one pair of electrons by two atoms

Question 24

Double covalent bond

Answer 24

When 2 Adams share 4 electrons two from each atom

Question 25

Non-polar covalent bonds

Answer 25

What electrons are shared equally between atoms

Question 26

Polar covalent bonds

Answer 26

Atoms that do not always share their electrons equally
