atomic number 84

Friendly

The term "atomic number 84" refers specifically to the chemical element called "polonium." Let's break this down to make it easier to understand:

Basic Explanation:

• Atomic Number 84: This is a scientific way to identify the element polonium. Every element on the periodic table has a unique atomic number, which tells us how many protons are in the nucleus of its atoms. In the case of polonium, there are 84 protons.

Characteristics:

• Polonium is a radioactive metallic element. This means it can change into other elements over time and release energy in the form of radiation.
• It is similar to other elements called tellurium and bismuth. These are also metals and have some similar properties.
• Polonium is found in uranium ores, which are rocks that contain uranium, a metal often used for nuclear energy.

Production:

• Polonium can also be produced in laboratories by bombarding bismuth with neutrons in a process that takes place in a nuclear reactor. This means scientists can create polonium by hitting bismuth atoms with tiny particles called neutrons.

Usage Instructions:

• You would typically use the term "atomic number 84" in scientific contexts, especially in chemistry or physics. For example, when discussing the periodic table or talking about radioactive materials, you might say, "Polonium has an atomic number of 84."

Example Sentence:

• "Polonium, with atomic number 84, is used in some types of smoke detectors and as a heat source in space equipment."

Advanced Usage:

• In more advanced discussions, you might talk about the applications of polonium in nuclear physics or its role in research. For example, "Due to its high radioactivity, polonium-210 (a common isotope of polonium) is studied for its potential uses and dangers in various fields."

Word Variants:

• The term "polonium" is the main variant related to atomic number 84.
• The word "radioactive" is an adjective that describes materials that emit radiation, including polonium.

Different Meanings:

• The term "atomic number" itself can be used more generally to describe any element on the periodic table, not just polonium. For example, "The atomic number of hydrogen is 1."

Synonyms:

• There aren't direct synonyms for "atomic number 84" as it is a specific scientific term, but you might encounter terms related to radioactive elements, such as "radioactive metal."

Idioms and Phrasal Verbs:

• There are no specific idioms or phrasal verbs related to "atomic number 84," but you might hear phrases like "go nuclear" which refers to using nuclear energy or weapons, though it doesn't specifically relate to polonium.
