question 9 1 pts isotopes are atoms that have the same ______ but differing ______. atomic masses, charges charges, atomic masses atomic numbers, mass numbers mass numbers, atomic numbers mass numbers, charges question 10 1 pts elements ______ exhibit similar physical and chemical properties. with similar chemical symbols in the same period of the periodic table on opposite sides of the periodic table with similar atomic masses in the same group of the periodic table

Answer

Brief Explanations:

For Question 9, isotopes are defined as atoms of the same element (same atomic number) with different numbers of neutrons, resulting in different mass numbers. For Question 10, elements in the same group of the periodic table have the same number of valence - electrons, which leads to similar physical and chemical properties.

Answer:

Question 9: C. atomic numbers, mass numbers Question 10: E. in the same group of the periodic table
