Atoms, Ions, and Molecules: Differences and Examples

Atoms, ions, and molecules are fundamental entities in chemistry, each with distinct characteristics:
Atoms:
🔹Composition: Atoms are the basic units of matter and the smallest indivisible particles of an element.
🔹Charge: Atoms are usually electrically neutral, with equal numbers of protons (positively charged) and electrons (negatively charged).
🔹Formation: Atoms combine to form molecules through chemical bonding.
Ions:
🔹Composition: Ions are charged particles that result from an atom gaining or losing electrons.
🔹Charge: Ions can be positively charged (cations) if they lose electrons or negatively charged (anions) if they gain electrons.
🔹Formation: Ions are formed through processes such as ionization or the interaction of atoms with other particles.
Molecules:
🔹Composition: Molecules are formed when two or more atoms chemically combine through bonding.
🔹Charge: Molecules are usually neutral, with the total positive charge equaling the total negative charge.
🔹Formation: Molecules result from covalent bonds (sharing electrons) between atoms of different or the same elements. These are usually non-metals.
So, atoms are the building blocks of matter, ions are charged particles derived from atoms, and molecules are combinations of atoms held together by chemical bonds.

I have come across a week before my exams. I cannot express how underappreciated it is! I will inform my classmates of this channel and its invaluable, fruitful insights that are presented in a manner that allows the brain to absorb the information like a sponge!

Hey thanks, great to hear! I have guides (free) on my website that organize many of my videos around topics, if you need it. www.Breslyn.org

Thank you Dr B once again , you're helping me a lot during my board exams ❤

[@wbreslyn]

All the best on those board exams, you got this!

[@AstheticYan]

​@@wbreslynThank you Sir , it means a lot❤

Hello sir, how are you ? i am from india ,i want to say about sodium azide , is it solid liquid or gas or anything else 🤔

[@wbreslyn]

It's an ionic compound so it will be a solid. Looks like this:
