LD Nuclear Chemistry Intro.

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is a radioactive element?

Back

A radioactive element is one that has an unstable nucleus and can decay over time, emitting radiation.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in an atom's nucleus.

Front

What is the difference between fission and fusion?

Back

Fission is the splitting of a heavy nucleus into smaller nuclei, while fusion is the combining of light nuclei to form a heavier nucleus.

Front

What is carbon dating used for?

Back

Carbon dating is used to determine the age of organic materials by measuring the amount of carbon-14 they contain.

Front

What does the symbol 16/7 N represent?

Back

It represents a nitrogen atom with a mass number of 16 and an atomic number of 7.

Front

What is an unstable nucleus?

Back

An unstable nucleus is one that has an imbalance of protons and neutrons, leading to radioactive decay.

Front

What is a beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (electron or positron) is emitted from an atomic nucleus.

Front

What is the significance of the periodic table's columns?

Back

The columns of the periodic table represent groups of elements that have similar chemical properties.
