Front

What is the electron configuration for a carbon atom?

Back

1s² 2s² 2p²

Front

Heisenberg's Uncertainty Principle states that it is impossible to know both the ___________ and the ___________ of a particle at the same time.

Back

position, velocity

Front

How many valence electrons does a carbon atom have?

Back

4

Front

What is the maximum number of electrons that an orbital can hold?

Back

2 electrons

Front

Is the following electron configuration correct? 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 4d¹⁰ 4p⁶ 5s¹? Why or why not?

Back

No. It should be 3d¹⁰ not 4d¹⁰.

Front

Define valence electrons.

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the significance of the electron configuration in chemistry?

Back

It determines how atoms interact and bond with each other.

Front

What does the Pauli Exclusion Principle state?

Back

No two electrons in an atom can have the same set of four quantum numbers.

Front

What is the shape of an s orbital?

Back

S orbitals are spherical in shape.

Front

What is the shape of a p orbital?

Back

P orbitals are dumbbell-shaped.
