Front

What type of orbitals do group 1 & 2 elements on the periodic table represent?

Back

s orbitals.

Front

What do isotopes have in common?

Back

Isotopes are two atoms that have the same number of protons but a different number of neutrons.

Front

Which element is most likely to behave as a noble gas based on periodic properties?

Back

Og (element 118).

Front

Which element has a full outer shell of valence electrons in its ground state?

Back

Neon.

Front

What is the closest orbital to the nucleus when writing electron configurations?

Back

1s orbital.

Front

What is the significance of the 's' orbital in electron configuration?

Back

The 's' orbital can hold a maximum of 2 electrons and is the first type of orbital filled in the electron configuration.

Front

What defines a noble gas?

Back

Noble gases have a full outer shell of electrons, making them stable and unreactive.

Front

How many electrons can the p orbital hold?

Back

The p orbital can hold a maximum of 6 electrons.

Front

What is the electron configuration for Neon?

Back

1s² 2s² 2p⁶.

Front

What is the difference between an atom and an ion?

Back

An atom is neutral, while an ion has a net charge due to the loss or gain of electrons.
