Answer

Brief Explanations:

Question 22:

The atomic number is equal to the number of protons. For a neutral atom, the number of electrons equals the number of protons. The mass number is the sum of protons and neutrons. So neutrons = mass number - atomic number = 24 - 10 = 14.

Question 23:

The atomic number is equal to the number of protons in the nucleus, not electrons in the nucleus.

Question 24:

Isotopes differ in the number of neutrons, not electrons.

Question 25:

In the chemical formula CH₄, the sub - script 4 after H indicates there are 4 hydrogen atoms and 1 carbon atom (when no sub - script is written for C, it is assumed to be 1).

Question 26:

In a mixture, there is no chemical bonding between components, while in compounds there is.

Question 27:

This is the definition of mixtures.

Answer:

  1. 14 neutrons
  2. False
  3. False
  4. There is one carbon and four hydrogen atoms.
  5. True
  6. True
