Question

True False Many atoms can gain or lose electrons to form ions, or atoms with electrical charges. Atoms of the same element with differing number of neutrons are ions. All atoms of each individual element have identical nuclei. Atoms in ground state have equal numbers of protons and electrons. All atoms of each individual element have the same numbers of neutrons.

Answer 1

Let's go through the statements one by one:

1. Many atoms can gain or lose electrons to form ions, or atoms with electrical charges.

   • True. Atoms can lose or gain electrons, resulting in positively charged ions (cations) or negatively charged ions (anions).

2. Atoms of the same element with differing number of neutrons are ions.

   • False. Atoms of the same element with differing numbers of neutrons are called isotopes, not ions. Ions are formed from the loss or gain of electrons.

3. All atoms of each individual element have identical nuclei.

   • False. While all atoms of a given element have the same number of protons in their nuclei (defining the element), they can have different numbers of neutrons (as in the case of isotopes), resulting in different atomic masses.

4. Atoms in ground state have equal numbers of protons and electrons.

   • True. In a neutral atom (the ground state), the number of protons equals the number of electrons, balancing the overall charge.

5. All atoms of each individual element have the same numbers of neutrons.

   • False. As mentioned earlier, atoms of an element can have different numbers of neutrons, leading to the existence of isotopes.

To summarize:

• 1: True
• 2: False
• 3: False
• 4: True
• 5: False
