atomic number 30

Friendly

The term "atomic number 30" refers to the element zinc in the periodic table of elements. Here’s an easy breakdown of what this means:

Basic Explanation:

• Atomic Number: This is a number that tells you how many protons are in the nucleus of an atom of an element. For zinc, this number is 30.
• Zinc: It is a bluish-white, shiny metal. It is not very strong at normal temperatures, meaning it can break easily, but it becomes softer and easier to shape when heated.

Usage Instructions:

• You can use "zinc" when talking about metals, chemistry, or materials. If you are discussing elements in science class, you could say, "Zinc has an atomic number of 30."

Example Sentence:

• "Zinc is commonly used in making alloys and is important for galvanizing iron to prevent rust."

Advanced Usage:

• In chemistry, you might encounter phrases like "zinc oxide" or "zinc sulfate," which are compounds made from zinc. In this context, you would refer to zinc's properties and reactions with other substances.

Word Variants:

• Zinc oxide: A compound made from zinc, often used in sunscreens and ointments.
• Zinc sulfate: Another compound that contains zinc, used in agriculture and as a dietary supplement.

Different Meanings:

• The word "zinc" primarily refers to the element itself, but in different contexts, it can refer to various compounds or uses of the metal (like in construction or medicine).

Synonyms:

• There aren’t exact synonyms for zinc, but you might refer to it as a "metal" or "element" in broader terms.

Idioms and Phrasal Verbs:

• There are no common idioms or phrasal verbs directly related to zinc, but you might hear phrases like "to galvanize" (which originally refers to the process of coating iron with zinc to prevent rust) used metaphorically to mean "to excite or energize someone into action."

Summary:

Zinc, or atomic number 30, is an important metal with various uses in everyday life.
