Metalloids make up the elements that line the line. Both metallic and nonmetallic qualities can be found in them. More electrons are typically gained than lost by the elements to the line's immediate right.
On the periodic table, the nonmetals are to the right of the stair-step line. In chemical processes, metals frequently lose electrons and produce positive ions.
<h3>What is Periodic Table ? </h3>
The chemical elements are shown in tabular form on the periodic table, sometimes referred to as the periodic table of the elements. It is frequently used in physics, chemistry, and other sciences and is frequently regarded as a symbol of chemistry.
<h3>What are Metalloids?</h3>
The term is usually applied to a group of six to nine elements (boron, silicon, germanium, arsenic, antimony, tellurium, and possibly bismuth, polonium, astatine) near the middle of the P block or main block of the periodic table increase.
- Metals are typically hard, bright, fusible, malleable, and ductile elements with excellent electrical and thermal conductivity.
- Non-metals are elements that do not have metallic properties. Metalloids are elements with properties intermediate between those of metals and nonmetals.
- In some cases, these elements are referred to as semimetals.
- Examples of metalloids include boron, silicon, tellurium, germanium, arsenic, antimony. Others include aluminum, astatine, polonium, etc.

3.0x10⁻²M
Explanation:
Silver sulfate, Ag₂SO₄, has a product constant solubility equilbrium of:
Ag₂SO₄(s) ⇄ 2Ag⁺ + SO₄²⁻
When an excess of silver sulfate is added, some Ag₂SO₄ will react producing Ag⁺ and SO₄²⁻ until reach the equilbrium determined for the formula:
ksp = 1.4x10⁻⁵ = [Ag⁺]² [SO₄²⁻]
Assuming the Ag₂SO₄ that react until reach equilibrium is X, we can replace in Ksp expression:
1.4x10⁻⁵ = [Ag⁺]² [SO₄²⁻]
1.4x10⁻⁵ = [2X]² [X]
1.4x10⁻⁵ = 4X³
3.5x10⁻⁶ = X³
0.015 = X
As [Ag⁺] is 2X:
[Ag⁺] = 0.030 = 3.0x10⁻²M
The answer is:
<h3>3.0x10⁻²M</h3>
Answer:
The percent composition of a component in a compound is the percent of the total mass of the compound that is due to that component. To calculate the percent composition of a component in a compound: Find the molar mass of the compound by adding up the masses of each atom.
