To determine the answers to these questions, let's break it down:
1. "Electrostatic interaction is important for which type of bond?"
To answer this question, we need to understand what electrostatic interaction is and which type of chemical bond relies on it. Electrostatic interaction refers to the attraction or repulsion between charged particles. In chemistry, it is commonly observed in ionic bonds, where positively and negatively charged ions are attracted to each other due to their opposite charges. So, the answer is A) ionic bond.
2. "When an atom gains or loses valence electrons and becomes charged, it is known as a(n) _____."
In this question, we are looking for the term that describes an atom that has gained or lost valence electrons, resulting in a charge. This is known as an ion. So, the answer is C) ion.
3. "When an atom loses electrons, its charge becomes _____."
Here, we need to determine the charge that an atom acquires when it loses electrons. When an atom loses electrons, it loses negatively charged particles, resulting in an overall positive charge. Therefore, the answer is B) positive.
4. "When an atom gains electrons, its charge becomes _____."
In this question, we need to identify the charge that an atom acquires when it gains electrons. When an atom gains electrons, it gains negatively charged particles, resulting in an overall negative charge. So, the answer is C) negative.
5. "An atom that has lost electrons and has become positively charged is called a(n) _____."
Here, we need to identify the term used to describe an atom that has lost electrons and acquired a positive charge. Such an atom is called a cation. Thus, the answer is C) cation.
6. "An atom that has gained electrons and has become negatively charged is called a(n) _____."
We are looking for the term used to describe an atom that has gained electrons and acquired a negative charge. Such an atom is called an anion. Therefore, the answer is D) anion.
7. "Three dimensional networks made by cations and anions surrounding each other are _____."
In this question, we need to identify the term used to describe three-dimensional networks formed by positively and negatively charged ions surrounding each other. This type of structure is characteristic of ionic solids. Thus, the answer is A) ionic solids.
