28 Terms

1

Nuclear fusion

Process in the sun's core where hydrogen atoms collide to form helium, releasing massive energy due to extreme conditions.

New cards
2

Sunspot

Darker area on the sun's surface caused by cooler temperatures compared to surrounding areas.

New cards
3

what are the 5 parts of the sun

Core, Radiative Zone, Convection zone, Photosphere, Chromosphere

New cards
4

Core

Hottest part of the sun located at its center.

New cards
5

Radiative Zone

Largest part of the sun where energy is transferred to the surface through conduction and radiation diffusion.

New cards
6

Convective Zone

transfer heat through convection currents with hot plasma rising, cooling at the surface, and then sinking back down.

New cards
7

Photosphere

Sun's outer shell emitting visible light.

New cards
8

Chromosphere

Hot atmosphere of the Sun above the photosphere.

New cards
9

Atomic number

Number of protons or electrons in an atom.

New cards
10

Atomic mass

Sum of protons and neutrons in an atom.

New cards
11

Atoms

building blocks of all matter with no overall charge.

New cards
12

Unstable Atoms

to many neutrons

New cards
13

Subatomic Particles

Protons+, Electrons-, Neutrons0, nucleus(P+N)

New cards
14

Elements

Pure substances consisting of only one type of atom.

New cards
15

Compounds

Substances with two or more types of atoms chemically bonded.

New cards
16

Mixtures

Combination of substances not chemically bound.

New cards
17

Molecules

Two or more atoms chemically bonded.

New cards
18

Molecule of an element and compound

molecules with either one type of atom or 2 or more types (compound)

New cards
19

Ions

Atoms or molecules with an electric charge.

New cards
20

Positive and Negative Ions

less electrons than protons, more electrons than protons

New cards
21

Ionic compounds

Atoms bond to form ions to achieve a full valence shell. (2,8,8)

New cards
22

Atmosphere

Earth's gaseous envelope composed mainly of nitrogen, oxygen, and water vapor.

New cards
23

Layers of atmospere

Trophosphere, Stratosphere, mesosphere, Thermosphere, Exosphere.

New cards
24

Troposphere

Lowest atmospheric layer with decreasing temperature at higher altitudes and convection currents.

New cards
25

Stratosphere

Layer with increasing temperature at higher altitudes and containing the ozone layer.

New cards
26

Mesosphere

Layer with decreasing temperature at higher altitudes and where meteoroids burn due to friction.

New cards
27

Thermosphere

Layer with increasing temperature at higher altitudes absorbing heat from UV rays.

New cards
28

Exosphere

Outermost layer of the atmosphere where particles can escape.
