which statements accurately describe trends found in the periodic table? check all that apply.\nhenry moseley established a periodic table that arranges the elements by atomic number.\nthe atomic mass decreases from left to right on the periodic table.\nthe atomic number increases from left to right on the periodic table.\nnonmetals create a \staircase\ down the periodic table.\nmetalloids have the characteristics of both metals and nonmetals.
Answer
# Brief Explanations:
- Henry Moseley arranged elements by atomic number.
- Atomic number increases left - to - right.
- Metalloids have metal and nonmetal characteristics.
- Atomic mass generally increases left - to - right (not decreases).
- Metalloids (not nonmetals) create a “staircase”.
# Answer:
First statement: Henry Moseley established a periodic table that arranges the elements by atomic number.
Third statement: The atomic number increases from left to right on the periodic table.
Fifth statement: Metalloids have the characteristics of both metals and nonmetals.
