Questions and Answers

1.

An ion forms when
- A.
  
  An atom loses or gains electrons
- B.
  
  An atom loses or gains neutrons
- C.
  
  An atom loses or gains protons
- D.
  
  Two elements combine
Correct Answer
A. An atom loses or gains electrons

Explanation
An ion forms when an atom loses or gains electrons. This process is known as ionization. When an atom loses electrons, it becomes positively charged and is called a cation. Conversely, when an atom gains electrons, it becomes negatively charged and is called an anion. The gain or loss of electrons is responsible for creating an imbalance in the atom's positive and negative charges, resulting in the formation of an ion.

2.

Positive ions are called anions and they lose electrons.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The given statement is incorrect. Positive ions are actually called cations, not anions. Cations are formed when an atom loses electrons, resulting in a net positive charge. Anions, on the other hand, are negatively charged ions formed when an atom gains electrons. Therefore, the correct answer is False.

Rate this question:
3.

Negative ions are called anions and they gain electrons.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Negative ions are called anions because they have gained electrons. Anions are formed when an atom or molecule gains one or more electrons, resulting in a negatively charged ion. Therefore, the statement is true.

Rate this question:
4.

A substance made from two or more different atoms is called a ________.

Correct Answer
Compound

Explanation
A substance made from two or more different atoms is called a compound. In a compound, the atoms are chemically bonded together, creating a new substance with unique properties. Compounds can be formed through various chemical reactions, such as the combination of elements or the reaction between an element and a compound. Examples of compounds include water (H2O), carbon dioxide (CO2), and sodium chloride (NaCl). Compounds play a crucial role in various fields, including chemistry, biology, and medicine. They are essential for the existence and functioning of living organisms and have numerous practical applications in industries.

5.

Positive ions can only combine with other positive ions and negative ions can only combine with other negative ions.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement that positive ions can only combine with other positive ions and negative ions can only combine with other negative ions is false. In reality, positive and negative ions can combine to form ionic compounds through the process of ionization. This occurs when a positively charged ion, known as a cation, is attracted to a negatively charged ion, known as an anion, resulting in the formation of a stable compound. Therefore, positive and negative ions can combine with each other to form compounds with a neutral charge.
