FAQs on Metals and Non-Metals - Chemistry, General Science, Exam Preparation Video Lecture - General Awareness & Knowledge - Bank Exams
| 1. What are metals and non-metals? |  |
Ans. Metals are a class of elements characterized by their ability to conduct heat and electricity, as well as their luster and malleability. Non-metals, on the other hand, are elements that generally do not possess these properties. They are usually poor conductors of heat and electricity and can be either solid, liquid, or gas at room temperature.
| 2. What are some examples of metals and non-metals? | |
Ans. Some examples of metals include iron, copper, gold, silver, and aluminum. Non-metals include elements such as carbon, oxygen, nitrogen, sulfur, and chlorine. It is important to note that elements can exhibit properties of both metals and non-metals depending on their specific characteristics.
| 3. How are metals and non-metals different in terms of chemical properties? | |
Ans. Metals tend to lose electrons and form positive ions, while non-metals tend to gain electrons and form negative ions. This fundamental difference in electron behavior leads to contrasting chemical properties. Metals are more likely to undergo oxidation (loss of electrons) and form cations, whereas non-metals are more prone to reduction (gain of electrons) and form anions.
| 4. What is the role of metals and non-metals in the periodic table? | |
Ans. Metals are typically found on the left side of the periodic table, occupying the majority of the elements. Non-metals, on the other hand, are primarily located on the right side of the table. This arrangement reflects the trend of increasing metallic character from right to left and top to bottom.
| 5. How do metals and non-metals react with each other? | |
Ans. Metals and non-metals can react with each other to form compounds. Typically, metals will transfer electrons to non-metals to achieve a stable electron configuration. For example, sodium (a metal) reacts with chlorine (a non-metal) to form sodium chloride, where sodium donates an electron to chlorine, resulting in the formation of an ionic compound.
