Question

reset the simulation (see directions between questions 3 and 4 if you need help). choose the elements sodium (na) and sulfur (s) from the periodic table. look at the side - by - side comparison. which element has a larger atomic radius? sodium sulfur question 7 1 pts answer the following question based on the data you recorded from the elements in periods 2 and 4. what is the general trend in atomic radius of atoms within the same period? the atomic radius increases from left to right within the same period. the atomic radius does not change within the same period. the atomic radius decreases from left to right within the same period. the atomic radius decreases from left to right within the same period.

Explanation:

1. Sodium and sulfur are in the same period (period 3). As you move from left - to - right across a period, the number of protons increases, pulling the electrons closer to the nucleus, thus reducing the atomic radius. Sodium is on the left of sulfur in the periodic table, so it has a larger atomic radius.
2. The general trend in atomic radius within the same period is that it decreases from left to right due to the increasing nuclear charge that attracts the electrons more strongly.

Answer:

1. Sodium
2. The atomic radius decreases from left to right within the same period.
