To answer these questions, we need to understand some basic concepts in chemistry.
1. Electrostatic interaction is important for which type of bond?
To determine this, we need to recall that electrostatic interaction refers to the attraction between positively and negatively charged particles. Ionic bonds are formed when ions (charged atoms or molecules) with opposite charges attract each other due to electrostatic interactions. Therefore, the answer is A) ionic bond.
2. When an atom gains or loses valence electrons and becomes charged, it is known as a(n) _____.
This question is testing our understanding of ions. When an atom gains or loses valence electrons, it becomes charged and forms an ion. The answer is C) ion.
3. When an atom loses electrons, its charge becomes _____.
Here, we need to determine the charge of an atom that loses electrons. When an atom loses electrons, it loses negative charges, making its charge more positive. Therefore, the answer is B) positive.
4. When an atom gains electrons, its charge becomes _____.
Similarly, we need to determine the charge of an atom that gains electrons. When an atom gains electrons, it gains negative charges, making its charge more negative. Therefore, the answer is C) negative.
5. An atom that has lost electrons and has become positively charged is called a(n) _____.
To answer this question, we need to recall the terms used to describe charged atoms. An atom that has lost electrons and becomes positively charged is called a cation. Therefore, the answer is C) cation.
6. An atom that has gained electrons and has become negatively charged is called a(n) _____.
Similarly, we need to recall the terms used to describe charged atoms. An atom that has gained electrons and becomes negatively charged is called an anion. Therefore, the answer is D) anion.
7. Three-dimensional networks made by cations and anions surrounding each other are _____.
Here, we need to recognize the description of a specific type of bonding. Three-dimensional networks made by cations (positively charged ions) and anions (negatively charged ions) surrounding each other are characteristic of ionic solids. Therefore, the answer is A) ionic solids.
