Question

5 Why do elements have different
properties?

Answer 1

Answer:

The basic building blocks are the same but the arrangement differs, in a very orderly manner according to quantum mechanical rules but different. Therefore each element, molecule, composite structure has its individual set of properties. Lets start small a one proton atom hydrogen has one electron when neutral, however, its orbital structure allows 2 electrons to be attracted to the nucleus so H is reactive and exists normally as H2 and H can also bond to many other different atoms. The Helium nucleus has 2 protons so the neutral molecule has 2 electrons in a filled orbital and has little tendency to lose, share or gain electrons so the He atom exists as a single atom, unreactive, molecule. As the nucleus increases in the number of protons[and neutrons another story] The number of energy levels and their complexity increases and the different kinds of reactivity multiply, Time to start reading the chemistry books.

A simple analogy bricks make a building how they are arranged tells what kind.

People and even other mammals and other life have essentially the same molecular buildup Yet we differ, different amounts, some kinds, and arrangement of molecules.

Answer 2

Answer:

elements have different properties

Explanation:

elements have different properties because they differ in atomic numbers and number of protons , neutrons and electrons they have
