Radiation and isotopes

Question 1

Radiation definition

Answer 1

The release of energy in the form of waves or particles

Question 2

Non-ionizing

Answer 2

A type of low-energy radiation that does not have enough energy to remove an electron

Question 3

Ionizing

Answer 3

A type of high-energy radiation that has enough energy to remove an electron

Question 4

3 types of radiation

Answer 4

a = alpha
b = beta
y = gamma

Question 5

Radioisotopes definition

Answer 5

An unstable form of a chemical element that releases radiation as it breaks down and becomes more stable.

Question 6

Radioactivity

Answer 6

The release of energy from the decay of the nuclei of certain kinds of isotopes

Question 7

Nuclear decay

Answer 7

The process by which an unstable atomic nucleus loses energy by radiation

Question 8

Half-life

Answer 8

The time required for a quantity (of substance) to reduce to half of its initial value

Question 9

Identifying factors of an element

Question 10

Groups of the periodic table

Question 11

Radioactive isotopes

Question 12

Science experiment stuff

Question 13

Graph the half life of iodine-125

Question 14

Isotopes

Answer 14

Atoms of an element with the same protons but different neutrons

Question 15

What determines if an isotope will be stable

Answer 15

• Neutron and proton ratio of 1:1
• Atomic number less then 83

Question 16

Radioisotopes

Answer 16

Unstable isotopes undergo a process called “spontaneous nuclear decay” where the nucleus becomes too heavy and breaks into two pieces. This releases a large amount of energy in the form of radiation.

Question 17

How would baking soda affect the size of the volcano

Answer 17

More baking soda creates more carbon dioxide gas when it reacts with vinegar. Bigger buildup of gas leads

Question 18

How would baking soda affect speed of the volcano

Answer 18

Speed up the reaction, as there would be more reactants available for the vinegar to break down.
