Unit 2 Honors Nuclear chemistry and the atom Deck 1

Guaranteed 100%

positron

alpha particle

[...] radiation includes things like alpha particles and beta particles and is dangerous because it causes atoms to loses electrons

Ionizing

gamma particle

Release of nuclear particle which is shown on product side

Decay or emission

[...] radiation includes things like radiowaves and visible light and does not affect the atom

Non-ionizing

Refers to a nuclear particle being placed on reactant side with electron capture being an example

absorption

Electrons exist in the electron cloud which is also known as a [...] or [...]

shell; energy level

A [...] has an unstable nucleus and emits radiation to become more stable

radioactive isotope

What are two things that Rutherford discovered about the atom

Most of the atom is empty space and the nucleus is positively charged

Isotopes are atoms that have the same number of protons and a different number of neutrons which leads to an atom having a different [...].

mass

Two types of nuclear reactions are [...] where two atoms combine to form a bigger atom and [...] where a heavy nucleus is split into two smaller nuclei. 

fusion; fission

Isotopes are atoms that have the same number of [...] and a different number of [...] which leads to an atom having a different mass.

neutrons; protons

Which subatomic particle(s) mass is 1 amu?

proton and neutron

proton

The time required for half of the atoms in any given quantity of a radioactive isotope to decay 

half life

neutron

The majority of the mass of the atom is located inside the [...] which is composed of [...] and [...]

nucleus; protons; neutrons

Illness or sickness caused by excessive exposure to radiation

Radiation poisoning

The three subatomic particles are [...] which have a positve charge, [...] which have a neutral charge and [...] which have a negative charge.

protons; neutrons; electrons

beta particle

[...] discovered the electron and came up with the [...] model of the atom

JJ Thompson; plum pudding

Coversion of one element to another through artificial means

transmutation
