As you move around there is a change in: electronegativies, ionisation energies, atomic radius etc. different amounts of these properties are going to effect how the element acts
Is divided by the same number that goes into the number being divided evenly so there are no remainers
example....

Answer:
by changing the number of protons in the atom
Explanation:
Elements are defined by their number of protons. For example, an element with 1 proton is hydrogen, and an element with 2 protons is helium. Changing the number of neutrons or electrons in a preexisting element will not make a new element. Is is possible to create new elements, but it requires large amounts of heat and/or pressure.
