Answer: substances that are made up of only one type of atom
Step-by-step explanation:
Element is a pure substance which is composed of atoms of similar elements. Example: Carbon (C)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water
The subatomic particles with a positive charge are called as protons and are located in the nucleus of the atom.
Thus elements are substances that are made up of only one type of atom.

Answer:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
Step-by-step explanation:
The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even
To prove this conjecture
unit digit = 6
hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
