heat, heat can change the state of matter therefore speeding up molecules.

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...
number of electrons in valence (last) shell
the properties of a compound are not the same as the elements that form them.
All elements have several properties.
Patterns in the elements’ properties. -Apex
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.
Yes. For example, combining gases oxygen and hydrogen gives you water. Combining sodium and chlorine (both dangerous and toxic elements) gives you common salt.
An Alloy is two metals mixed together.it is the combination of one or more elements, usually metals. the mixture of elements in an alloy gives it new properties that are different from the properties of the individual element. it often eliminates disadvantages of the pure metal .
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.
