Nuclear Chemistry

Question 1

WHat does electron arrangement determin

Answer 1

chemical proterties

Question 2

What is nuclear chem

Answer 2

concerned with changes in the nucleaus
results in transformation from one elment to another
always has emission of radiation

Question 3

Type of electromagnetic waves and what they are

Answer 3

Ionization radiation - waves or particles that carry enough eng to remove an electron from an atom
Nuclear rradiation - type of ionizing radiation that comes from the nucleus

Question 4

what is a radioisotope

Answer 4

substance that emits nuclear radiation

Question 5

What are the types of nuclear radiation

Answer 5

1. Alpha particles
   ▪ Stream of fast-moving helium nuclei
2. Beta particles
   ▪ Stream of fast-moving electrons
3. Gamma rays
   ▪ High frequency electromagnetic radiation
   ▪ Often emitted along with alpha and beta radiation

Question 6

waht happens iwth alpha decay

Answer 6

a helium is released
(2 protons 2 neutrons )
atomic number ad mass number change
new element
is lslow

Question 7

What happens in Beta decay

Answer 7

an electron is emitted
atomic number is changed, new element
is fast

Question 8

What is gamma decay

Answer 8

No change in mass or charge
very fast moving
usually happens after the emission of a decay particle

Question 9

Nuclear vs chemical reactions

Answer 9

Nuclear: diff isotope behave diff
- reactions not affected by chem state
- eng change is large
Chemical : diff isotope behave same
- reactions depend on chem state
- eng change is small
