The Modern Atomic Theory

Question 2 • *26-27 CFISD TX-Chemistry A CR

Check the statements that are a part of the Early Atomic Theory. Check all of the boxes that apply

Answer
A
Scientists believe that the atom is made up of elements.
B
Atoms combine in whole number ratios to form compounds.
C
Atoms cannot be created or destroyed during a chemical reaction.

Explanation

Early atomic theory states that atoms combine in simple whole-number ratios to form compounds, so B is correct. It also states that atoms are not created or destroyed during a chemical reaction; they are rearranged, so C is correct. A reverses the relationship: elements are made of atoms, rather than atoms being made up of elements.
