On Ramps Chemistry Midterm 1 Review

Front

What happens when an electron emits light?

Back

The electron 'calms down' and 'drops back down' closer to the nucleus.

Front

Which color of light has the greatest energy per photon?

Back

Violet.

Front

Which of the following is not a stable p block metal ion?

Back

Tl⁺⁴.

Front

What is not an example of a trend or electronic configuration exception based on filled or half filled shells and subshells?

Back

Atomic radius.

Front

Which statement is not true about electronic configurations?

Back

The subshells each contain the same number of electrons.

Front

Define the Aufbau principle in electron configuration.

Back

Electrons occupy the lowest energy orbitals first.

Front

What is Hund's rule?

Back

Every orbital in a subshell is singly occupied before any orbital is doubly occupied.

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 significance of filled and half-filled subshells in stability?

Back

Filled and half-filled subshells are more stable due to lower energy configurations.

Front

How does ionization energy change across a period?

Back

Ionization energy generally increases across a period from left to right.
