- Chemistry is concerned with structure and transformations of matter on an atomic level. Atoms come together to form compounds and compounds can break apart into atoms or be combined to form new compounds.
Structure of Atoms
Atoms are the building blocks of the universe; they make up everything you see around you. But what makes up an atom?
Electronic Structure Of Atoms Pdf
At the very center of an atom is the nucleus, which is made up of small particles called protons and neutrons. Protons are very small, positively-charged particles, and neutrons are neutral particles that have no charge.

https://treepico749.weebly.com/download-mac-sierra-1012-dmg.html. Atoms can have just one proton or they can have multiple. A group of atoms that all have the exact same number of protons are called an element. For example, hydrogen is an element with one proton in the nucleus and carbon is an element with 6 protons.
In general, an atom will have a specific number of neutrons in the nucleus, meaning the atom won’t lose or gain any neutrons for a very long time. Windows dvd maker software. This is called a stable atom. Usually, a stable atom has an equal number of neutrons and protons, but there are exceptions. To find the mass number of an element you add the number of protons and neutrons together, so protons + neutrons = mass number. This gives us names like Carbon-12 or Carbon-14, which are types of carbon atoms used in carbon dating!
Orbiting the atom’s positively-charged center are particles with a negative charge called electrons. The electrons are attracted to the positive nucleus, but they can escape their orbit by an outside force.
Atoms have a certain number of electrons orbiting the nucleus. If the number of electrons is equal to the number of protons, the overall electric charge of the atom is neutral. If the atom has more electrons than protons, its charge will be negative. With fewer electrons than protons, the atom will have a positive charge.
The electrons determine how atoms interact with each other. Atoms can share electrons to form molecules, which are particles made up of many atoms. Water is made up of two hydrogen atoms and one oxygen atom. These three atoms share electrons.

Now that we have talked about the different parts of the atom, let’s summarize a few properties of atoms. Atoms have an atomic number, which is the number of protons in the nucleus. The periodic table arranges atoms in increasing atomic number. The charge of an atom is calculated based on the difference between the number of protons in the nucleus and the number of electrons orbiting the nucleus.

Here’s a quick review:
An atom is made up of protons, electrons, and neutrons. The number of electrons will determine how atoms interact with one another and decide if the atom as a whole is positive, negative, or neutral. The mass number of an atom is found by adding together the number of protons and neutrons. And finally, the charge of an atom is determined by the number of protons and electrons in the atom.
Thank you so much for watching, and see you guys next time!
Atoms are one of the first topics covered in a chemistry course because they are the fundamental building block of matter. Atoms bond to each other to form pure elements, compounds, and alloys. These substances exchange atoms with each other to form new products through chemical reactions.
Key Takeaways: Atoms
- Atoms are the smallest unit of matter that cannot be divided using any chemical method. They do consist of smaller parts, but can only be broken by nuclear reactions.
- The three parts of an atom are protons, neutrons, and electrons. Protons carry a positive electrical charge. Neutrons are electrically neutral. Electrons carry a negative charge, equal in magnitude to that of a proton.
- Protons and neutrons stick together to form the atomic nucleus. Electrons orbit around the nucleus.
- Chemical bonding and chemical reactions occur due to the electrons around atoms. An atom with too many or too few electrons is unstable and may bond with another atom to either share or essentially donate electrons.
Atom Overview
Chemistry is the study of matter and the interactions between different types of matter and energy. The fundamental building block of matter is the atom. An atom consists of three main parts: protons, neutrons, and electrons. Protons have a positive electrical charge. Neutrons have no electrical charge. Electrons have a negative electrical charge. Protons and neutrons are found together in what is called the nucleus of the atom. Electrons circle around the nucleus.

Chemical reactions involve interactions between the electrons of one atom and the electrons of another atom. Atoms which have different amounts of electrons and protons have a positive or negative electrical charge and are called ions. When atoms bond together, they can make larger building blocks of matter called molecules.

The word 'atom' was coined by the early Greeks Democritus and Leucippus, but the nature of the atom wasn't understood until later. In the 1800s, John Dalton demonstrated atoms react with each other in whole ratios to form compounds. The discovery of the electron earned J.J. Thomson the 1906 Nobel Prize in Physics. The atomic nucleus was discovered in the gold foil experiment conducted by Geiger and Marsden under the supervision of Ernest Rutherford in 1909.

- Atoms cannot be divided using chemicals. They do consist of parts, which include protons, neutrons, and electrons, but an atom is a basic chemical building block of matter.
- Each electron has a negative electrical charge.
- Each proton has a positive electrical charge. The charge of a proton and an electron are equal in magnitude, yet opposite in sign. Electrons and protons are electrically attracted to each other.
- Each neutron is electrically neutral. In other words, neutrons do not have a charge and are not electrically attracted to either electrons or protons.
- Protons and neutrons are about the same size as each other and are much larger than electrons.
- The mass of a proton is essentially the same as that of a neutron. The mass of a proton is 1840 times greater than the mass of an electron.
- The nucleus of an atom contains protons and neutrons. The nucleus carries a positive electrical charge.
- Electrons move around outside the nucleus.
- Almost all of the mass of an atom is in its nucleus; almost all of the volume of an atom is occupied by electrons.
- The number of protons (also known as its atomic number) determines the element. Varying the number of neutrons results in isotopes. Varying the number of electrons results in ions. Isotopes and ions of an atom with a constant number of protons are all variations of a single element.
- The particles within an atom are bound together by powerful forces. In general, electrons are easier to add or remove from an atom than a proton or neutron. Chemical reactions largely involve atoms or groups of atoms and the interactions between their electrons.
