He (disambiguation) facts for kids

He is a short word that can mean two very different things! It can be a word we use when talking about a boy or man, or it can be the special symbol for a gas called Helium. Understanding which "He" is being used depends on the sentence or topic.

What Does "He" Mean as a Pronoun?

When you see "He" in a sentence, it often acts as a Pronoun. A pronoun is a word that takes the place of a noun. This helps us avoid repeating the same name over and over again. "He" is specifically used to refer to a single male person or sometimes a male animal.

When Do We Use "He"?

We use "he" when we are talking about a boy, a man, or a male animal that has already been mentioned. For example, instead of saying "John went to the park. John played on the swings," you can say "John went to the park. He played on the swings." This makes sentences flow better and sound more natural.

Examples of "He" in Sentences

• "My brother loves to read. He always has a book with him."
• "The teacher explained the lesson. He made it easy to understand."
• "The dog wagged its tail. He was happy to see us."

Using "he" correctly is an important part of learning English grammar.

What Does "He" Mean as a Chemical Symbol?

In the world of Chemistry, "He" has a completely different meaning. It is the official symbol for the chemical element Helium. Every chemical element has a unique symbol, usually one or two letters. These symbols are used all over the world, so scientists can understand each other no matter what language they speak.

What is Helium?

Helium is a very special chemical element. It is a Noble gas, which means it doesn't easily react with other elements. It is also the second lightest element in the entire Universe, right after Hydrogen. Helium is colorless, odorless, and tasteless.

Where is Helium Found and Used?

Helium is found in huge amounts in space, especially in stars like our Sun. On Earth, it is much rarer. We usually find it trapped underground with natural gas. Because it is so light, Helium is famous for making balloons float. It is also used in many important ways, such as:

• Cooling powerful Magnets in MRI machines for hospitals.
• Creating a safe atmosphere for divers working deep underwater.
• Helping to inflate Airbags in cars very quickly.
• Used in some types of welding to protect metals.

So, when you see "He" in a science book, you know it's talking about the amazing element Helium!
