atomic number 94

Friendly

The term "atomic number 94" refers specifically to the element plutonium. Here’s a simple breakdown of what it is and how to understand it:

Definition:

• Atomic Number 94: This is the scientific term for plutonium, which is a chemical element with the symbol Pu. It is a solid, silvery-grey metal that is radioactive and belongs to a group of elements called transuranic elements (elements that come after uranium in the periodic table).

Key Features:

• Radioactive: This means that plutonium can emit radiation and is not stable over time.
• Transuranic: This indicates that plutonium is heavier than uranium.
• Isotopes: Plutonium has 13 known isotopes, which are different forms of the same element that have varying numbers of neutrons. The most important isotope for nuclear reactions is plutonium-239.

Usage Instructions:

• You can use "atomic number 94" when discussing chemistry, physics, or topics related to nuclear energy.
• Typically, you would say "plutonium" in everyday conversation, but "atomic number 94" is more precise and used in scientific contexts.

Example Sentences:

1. In chemistry class, we learned that plutonium has the atomic number 94.
2. Scientists have synthesized plutonium in nuclear reactors because it is not commonly found in nature.

Advanced Usage:

• In nuclear physics, discussions might revolve around the properties of plutonium-239 and its use in nuclear weapons and fuel.
• Researchers may refer to "atomic number 94" when discussing the periodic table or the behavior of different elements in nuclear reactions.

Word Variants:

• Plutonium (noun): The element itself.
• Plutonium-239 (noun): The specific isotope used in nuclear reactions.

Different Meanings:

• Generally, "atomic number 94" has a specific meaning in chemistry. The term does not have multiple meanings outside of the scientific context.

Synonyms:

• There are no direct synonyms, but you can refer to plutonium simply as Pu (its chemical symbol) in scientific discussions.

Idioms and Phrasal Verbs:

• There are no common idioms or phrasal verbs associated with "atomic number 94," as it is a technical term.

Summary:

"Atomic number 94" is a scientific term for the element plutonium, known for its radioactive properties and importance in nuclear chemistry.
