What subshell is being filled for the metalloid elements?

Short Answer

Expert verified
The p subshell is being filled for metalloid elements.

Step by step solution

01

Understanding Metalloids

Metalloids are elements found along the 'stair-step' line on the periodic table and have properties intermediate between metals and non-metals. Common metalloids include boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and polonium (Po).
02

Locating the Elements

To find which subshell is being filled, we locate the metalloids on the periodic table. They are typically found in the p-block, specifically from groups 13 to 17.
03

Identifying the Subshell

The periodic table is divided into blocks (s, p, d, f) based on which subshell is being filled. The elements in groups 13 to 17 are filling the p subshell.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Understanding Metalloids
Metalloids are fascinating elements known for their mixed characteristics. They possess traits of both metals and non-metals. This unique combination gives them the ability to conduct electricity better than non-metals but not as efficiently as metals. You can spot them on the periodic table along the 'stair-step' or zigzag line, marking the boundary between metals and nonmetals.

Common examples of metalloids include:
  • Boron (B)
  • Silicon (Si)
  • Germanium (Ge)
  • Arsenic (As)
  • Antimony (Sb)
  • Tellurium (Te)
  • Polonium (Po)
These elements play crucial roles in technology and industry due to their semiconductive properties.
Exploring the p-block
The periodic table is strategically divided into several blocks 鈥� namely s, p, d, and f blocks 鈥� based on the outermost subshell that electrons occupy. The p-block is particularly significant as it contains a diverse range of element types including metalloids, non-metals, and metals.

It spans across groups 13 to 18 and includes elements that naturally fill the p subshell as electrons add in sequential order across the period. Metalloids are found in groups 13 through 17, showing just how versatile and important this block is. This block hosts elements like oxygen and carbon, essential for life, as well as countless other useful substances.
Understanding Subshells
In the study of chemistry, subshells are crucial to understanding electron configuration and element properties. A subshell is a division of electron shells and contains orbitals where electrons reside. Each subshell is denoted by specific labels: s, p, d, and f.

For metalloids in the p-block, the p subshell is the key. This subshell can hold a total of six electrons and comprises three orbitals. The filling order of these subshells follows the Aufbau principle, which outlines the sequence electrons are added: first filling lower energy levels before higher ones. This principle helps explain both elemental behaviors and chemical reactions.

Identify the valence subshell occupied by electrons in beryllium and arsenic atoms.

Tellurium \((Z=52)\) has a lower atomic number than iodine \((Z=53)\), yet it has a higher atomic mass (127.60 amu for Te vs. 126.90 amu for I). How is this possible? Can you find any other instances in the periodic table where two adjacent elements exhibit a similar behavior, that is, the element with the lower atomic number has a higher atomic mass?
