Comptency 1 Part 2

Question 0

When an alpha particle leaves the nucleus is the element still the same ?

Answer 0

No element is not the same because it looses a proton and protons determine what an element is.

Question 1

What is an alpha particle made of ?

Answer 1

Two protons and two neutrons and it has a mass of 4

Question 2

What is transmutation?

Answer 2

The changing of an element by an alpha decay

Question 3

What is alpha decay?

Answer 3

Alpha decay is when a radiation particle is released from an atom

• breaking apart on their own

Question 4

What is fusion?

Answer 4

Fusion is the process of combing two light atoms to form a heavier one

*combining together

Question 5

What does fusion release?

Answer 5

Fusion releases energy that we can use for electricity

Question 6

What keeps the structure of atoms together?

Answer 6

The electric force between negative charge and positive charge of an electron and proton

Question 7

What is a chemical reaction?

Answer 7

A chemical reaction is combining two different elements together to form a new element.

Question 8

What is fission ?

Answer 8

Fission is when a neutron hits an atom causing it to split apart into two, releasing energy and three neutrons that go on and repeat the process.

Process of splitting a heavy atom into a lighter atom.
* splitting apart

Question 9

What are isotopes?

Answer 9

Isotopes are the same electrons with different mass (different number of neutrons) and same number of protons.

Question 10

Radioactive decay

Answer 10

When an unstable atom breaks a piece of itself to make it stable

Question 11

What are the elements that are essential for life?

Answer 11

Hydrogen, Iron, Oxygen, Potassium, Zinc

Question 12

What is radioactive decay?

Answer 12

When an unstable atom breaks a piece of itself.

Question 13

One parent nucleus breaking apart

Answer 13

Decay

Question 14

A neutron splits a large atom making neutrons.

Answer 14

Fission

Question 15

How does Uranium 238 help prevent from a nuclear meltdown?

Answer 15

It absorbs the neutrons and prevents the Uranium 235 from breaking apart.

Question 16

Describe the nuclear process of fusion that makes up different forms of matter within stars.

Answer 16

Stars, nuclei are fused together by the amount of gravity in a star. Fusion is the process of combining smaller nuclei into larger/heavier nuclei

Question 17

What is the sun made from? Fusion, fission, or nuclear decay?

Answer 17

Fusion - it is a process of elements that gather at the heat source to combine and expand and will eventually implode on itself and expand more. It starts off with stars imploding and creating a super nova and expanding the universe.
