What is atomic structure in your own words?
Atomic structure refers to the structure of an atom comprising a nucleus (centre) in which the protons (positively charged) and neutrons (neutral) are present. The negatively charged particles called electrons revolve around the centre of the nucleus.
What is the vocabulary for atomic number?
Scientists use the term atomic number to describe the number of protons in one atom of an element. For example, the atomic number of hydrogen is 1. If you’ve ever taken a chemistry class, you’ve seen a chart called “the periodic table of elements.” It lists every chemical element and each element’s atomic number.
What is the main definition of atom?
An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.
What is atom definition with example?
An atom is any particle of matter at its most basic level which contains at least one proton. Here are some examples of the atoms: hydrogen (H) and neon (Ne).
What is the vocabulary for element?
An element is something basic and important — in chemistry, an element is one of the essential molecules that everything else is made of. If a book’s ending carries an “element of surprise,” it means surprise is an important part of the story’s end.
What is the vocabulary of nucleus?
A nucleus is often called the brain, or control center, of a eukaryotic cell (that is, a cell with a nucleus). The noun nucleus has several senses, though most of them will appear in science.
What is an atom Definition & Examples?
What are 5 types of atoms?
Different Kinds of Atoms
- Description. Atoms are made of tiny particles called protons, neutrons and electrons.
- Stable. Most atoms are stable.
- Isotopes. Every atom is a chemical element, like hydrogen, iron or chlorine.
- Radioactive. Some atoms have too many neutrons in the nucleus, which makes them unstable.
- Ions.
- Antimatter.

What is the definition of the word mitochondria?
Definition of mitochondrion : any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes — see cell illustration.
What are 5 examples of atoms?

- Neon (Ne)
- Hydrogen (H)
- Argon (Ar)
- Iron (Fe)
- Calcium (Ca)
- Deuterium, an isotope of hydrogen that has one proton and one neutron.
- Plutonium (Pu)
- F-, a fluorine anion.
