Question

What are the symbols of the following metals: sodium, radium, iron, gold, manganese, lead?

Short answer

The symbols of the metals are: Sodium: \(Na\), Radium: \(Ra\), Iron: \(Fe\), Gold: \(Au\), Manganese: \(Mn\), and Lead: \(Pb\).

Step-by-step solution

Referring to the Periodic Table of Elements

To find the symbols of the metals, refer to the Periodic Table of Elements. Each element in the periodic table has a unique symbol that represents the element.

Find the symbol for Sodium

Look for Sodium in the Periodic Table. Sodium's atomic number is 11 and its symbol is \(Na\).

Find the symbol for Radium

Look for Radium in the Periodic Table. Radium's atomic number is 88 and its symbol is \(Ra\).

Find the symbol for Iron

Look for Iron in the Periodic Table. Iron's atomic number is 26 and its symbol is \(Fe\).

Find the symbol for Gold

Look for Gold in the Periodic Table. Gold's atomic number is 79 and its symbol is \(Au\).

Find the symbol for Manganese

Look for Manganese in the Periodic Table. Manganese's atomic number is 25 and its symbol is \(Mn\).

Find the symbol for Lead

Look for Lead in the Periodic Table. Lead's atomic number is 82 and its symbol is \(Pb\).

The symbols of the metals are:

Sodium: \(Na\) Radium: \(Ra\) Iron: \(Fe\) Gold: \(Au\) Manganese: \(Mn\) Lead: \(Pb\)

Key concepts

Periodic Table

The Periodic Table is an essential tool used in chemistry and science education worldwide. It organizes all known chemical elements in a structured way based on their atomic number, electron configuration, and recurring chemical properties. Each element on the table is represented by a unique symbol, often derived from its name in English or Latin. By using the periodic table, one can easily find information about the properties of elements, how they relate to one another, and predict chemical reactions. For instance, you can identify metals, non-metals, and metalloids depending on their position on the table.

Metal Symbols

In the world of chemistry, metals are elements known for conducting electricity, being malleable, and having shiny appearances. Each metal in the periodic table is represented by a specific chemical symbol. The symbol is usually one or two letters long; the first letter is always uppercase, and if there's a second letter, it is lowercase. For example:

• Sodium is denoted by the symbol \(Na\), derived from its Latin name, 'Natrium.'
• Iron uses the symbol \(Fe\), from the Latin word 'Ferrum.'
• Gold's symbol is \(Au\), which comes from 'Aurum.'

By knowing these symbols, one can efficiently read and write chemical equations and understand scientific literature.

Atomic Number

The atomic number of an element is a fundamental property that defines what the element is. It refers to the number of protons found in the nucleus of an atom of the element. This number is displayed above the element's symbol in the periodic table. For example:

• Sodium has an atomic number of 11.
• Iron has an atomic number of 26.
• Gold has an atomic number of 79.

Knowing the atomic number of an element helps determine its position in the periodic table and identify its chemical behavior during reactions.

Chemical Elements

Chemical elements are pure substances consisting of only one type of atom. Each element is assigned a unique name and symbol that distinguishes it from others. On the Periodic Table, elements are categorized based on similar properties, including metals, non-metals, and metalloids. This categorization helps chemists understand how elements will interact with each other in chemical compounds and reactions. In this context, the knowledge of chemical elements and their symbols is crucial for writing chemical formulas and balancing chemical equations.
By understanding basic concepts of chemical elements, one can better explore the vast domain of chemistry and the intricate patterns of elements within the periodic table.
