The properties of the elements are changed.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
i think it is a earth have spoilt.

the properties of a compound are not the same as the elements that form them.
All elements have several properties.

The properties of the compound will differ from the properties of the elements of which it is made.
No two elements have the same properties.
The properties of the elements are changed.
A substance that has properties different from the chemical elements in it is a chemical compound. A chemical compound is built from chemical elements that are chemically bonded together. And the "finished product" will have chemical properties that are unique to that compound, and different from the properties of the substances that make it up.
he properties of salts are different from the properties of elements that go into making them
elements are a compourn of THEIR properties
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
