Flashcard Set on Atomic Structure and Chemistry

Front

What is an atom?

Back

The atom is the smallest unit of matter that retains the chemical properties of an element. It consists of a nucleus and subatomic particles.

Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom and determine the identity of the element.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom that help stabilize it.

Front

What are electrons?

Back

Electrons are negatively charged particles that orbit around the nucleus of an atom and influence the chemical properties of the element.

Front

What is the nucleus?

Back

The nucleus is the central part of the atom, composed of protons and neutrons, and is very dense.

Front

What is the atomic number?

Back

The atomic number is the number of protons in a nucleus and identifies an element in the periodic table.

Front

What are isotopes?

Back

Isotopes are variants of an element that have the same number of protons but a different number of neutrons.

Front

What is the Bohr model?

Back

The Bohr model is a representation of the atom in which electrons orbit the nucleus in defined energy levels.

Front

What are chemical compounds?

Back

Chemical compounds are substances formed from two or more elements that are joined together by chemical bonds.

Front

What are chemical properties?

Back

Chemical properties are the characteristics of an element that determine how it can react with other elements.
