Unit 7: Atomic Structure & Periodic Table

Front

What is the atomic structure of an atom?

Back

An atom consists of a nucleus containing protons and neutrons, with electrons orbiting around the nucleus.

Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom.

Front

What are electrons?

Back

Electrons are negatively charged particles that orbit the nucleus of an atom.

Front

What is an electron transition?

Back

An electron transition occurs when an electron gains or loses energy and moves between different energy levels or orbitals.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

What is the noble gas family?

Back

The noble gas family consists of elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

Which element is in the noble gas family?

Back

Xenon (Xe) is an example of an element in the noble gas family.

Front

What are alkaline metals?

Back

Alkaline metals are elements in Group 1 of the periodic table, known for being highly reactive and having one valence electron.

Front

What are halogens?

Back

Halogens are elements in Group 17 of the periodic table, known for being highly reactive nonmetals.
