Answer:
Halogens are highly reactive
An ionic compound is composed of ionic bonds that are formed by transfer of electrons from one atom to the other. The atom that loses electrons acquires a positive charge (cation) while that which gains electrons acquires a negative charge.
In the case of sodium chloride; Sodium Na has 1 electron in its outer orbital while Chlorine Cl has 7 electrons. Thus, Cl requires 1 electron to complete its octet. This electron is donated by Na.
Thus, NaCl is essentially, Na⁺Cl⁻
Ans D) Chlorine becomes an anion by gaining an electron from sodium
Extensive properties, as volume and mass, depend on the amount of material. So, you can have a sample of gold and a sample of copper with the same volume as long as you have different amount of each one.
On the other hand, intensive properties do not depend on the amound of material but on the chemical constitution of the material. Density is an intensive property, so gold and copper have different densities. That is why you can use intensive properties to characterize different materials.
Answer:
Functional groups.
Explanation:
Functional groups are the specific substituents present within the molecules which are responsible for characteristic chemical properties the molecule shows.
Glucose contains alcohol and aldehyde group while hexanoic acid contains carboxylic acid group. <u>The presence different types of the functional groups in both the compounds results in the difference in the properties of both the compounds.</u>
