Semester 2 Chemistry Review

Front

What is the melting point of a substance?

Back

The temperature at which a solid becomes a liquid.

Front

What is the melting point of the sample if it is -60 ºC?

Back

The sample melts at -60 ºC, indicating it is a solid at temperatures above this point.

Front

How many p orbitals are there in a sublevel?

Back

There are 3 p orbitals in a p sublevel.

Front

What is the electron configuration for Zinc?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰.

Front

What is the correct order of the visible light spectrum starting with the longer wavelength?

Back

Red, orange, yellow, green, blue, indigo, violet.

Front

How many d orbitals are there in a given sublevel?

Back

There are 5 d orbitals in a d sublevel.

Front

Define the term 'sublevel' in chemistry.

Back

A sublevel is a division of an energy level in an atom, containing orbitals of the same type.

Front

What is the significance of the visible light spectrum?

Back

It represents the range of wavelengths of light visible to the human eye.

Front

What is the relationship between wavelength and energy in the electromagnetic spectrum?

Back

Longer wavelengths correspond to lower energy, while shorter wavelengths correspond to higher energy.

Front

What is an orbital in atomic theory?

Back

An orbital is a region in an atom where there is a high probability of finding electrons.
