Chapter 4: Problem 53

The atomic number of yttrium, which follows strontium in the periodic table, exceeds the atomic number of strontium by one. Barium is 18 atomic numbers after strontium but it falls directly beneath strontium in the periodic table. Does strontium share more properties with yttrium or barium? Explain your answer.

Short Answer

Expert verified
Strontium shares more properties with Barium than with Yttrium. This is because Strontium and Barium belong to the same group (Group 2: Alkaline earth metals) in the periodic table.

Step by step solution

01

Understand the Position of Elements on the Periodic Table

In the periodic table, elements with similar properties are grouped together in columns, often called groups. Strontium is in Group 2 (Alkaline earth metals). Yttrium is in Group 3 while Barium is in the same group as Strontium, Group 2.
02

Analyze the Atomic Numbers

The atomic number determines the elements' location on the periodic table. In this question, it is stated that Yttrium's atomic number exceeds Strontium's by one and Barium is 18 atomic numbers after Strontium. The fact that these elements are all in sequence doesn't mean they share similar properties.
03

Comparative Analysis

Based on their positions on the periodic table, Strontium would share more properties with Barium as they are in the same group, Group 2. Although Yttrium follows Strontium on the periodic table in terms of atomic number, it doesn't mean it shares more properties with Strontium. In the periodic table, elements in the same group commonly share more properties because they have the same number of valence electrons, which most influence their chemical behavior.
