Students were asked over to answer a question at schools and to mention what is most important for them to succeed. One which response stood out from the rest was practice. People who absolutely successful do not become successful by being born. They work hard and determination their lives to succeeding. If you would like to accomplish your goals, keep this in mind! the following are one of the answer and question example that you could actually benefit from to practice and further enhance your practical knowledge and also give you insights that could assist you to preserve your study in school.
Question:
Which statement is generally true about CaCl2? It has only metallic bonds between the atoms. It has only covalent bonds between the atoms. Its bonds are formed by large differences in electronegativity. Its bonds are formed by small differences in electronegativity.
Answer:
Answer: Its bonds are formed by large differences in electronegativity.
Explanation:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.
Covalent bond is formed by sharing of electrons between non metals.
As electronegativity of calcium is 1 and that of chlorine is 3.16, there is a difference of (3.16-1) =2.16, which is large and thus form ionic bond.
They will possibly hopefully assist the student solve the question by implementing the questions and answer examples. Then would possibly make some sharing in a group discussion and also study with the classmate in relation to the topic, so another student also obtain some enlightenment and still keeps up the school learning.
