Question

This question is about elements in the periodic table. What property was used to arrange elements in early periodic tables? Tick (surd ) one box. Atomic number square Atomic weight square Mass number square

Answer 1

Atomic weight

Answer 2

## Step 1:The early periodic tables were arranged based on a property of the elements. The options provided are atomic number, atomic weight, and mass number. ## Step 2:The atomic number is the number of protons in an atom's nucleus and is unique to each element. However, this was not the property used to arrange early periodic tables.## Step 3:The mass number is the total number of protons and neutrons in an atom's nucleus. This was also not the property used to arrange early periodic tables.## Step 4:The atomic weight, also known as atomic mass, is the average mass of atoms of an element. This was indeed the property used to arrange early periodic tables. ### The formula used here is: **Atomic weight = (Number of protons x 1.00784) + (Number of neutrons x 1.00866)**
