Question

How can a new element be made?

by changing the number of neutrons in the atom

by changing the number of protons in the atom

by changing the number of electrons in the atom

new elements cannot be made from existing elements

​

Answer 1

by changing the number of protons in the atom

Step-by-step 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.
