Hola, iam James Agena, Hope you’re doing good!
Wow, 21 neutrons and 18 electrons - that’s a lot of particles! It’s no wonder why chemistry can be so complicated. But, with the right knowledge, it doesn’t have to be a total mystery. Let’s take a closer look at these two particles and see what they can tell us about the world around us.
What Has 19 Protons And 21 Neutrons And 18 Electrons? [Solved]
Well, it’s gotta be potassium! No doubt about it.
- Neutrons: Subatomic particles that have no charge and are found in the nucleus of an atom.
- Electrons: Negatively charged subatomic particles that orbit the nucleus of an atom.
- Atomic Number: The number of protons in an atom, which is equal to the number of electrons in a neutral atom (21 neutrons and 18 electrons).
- Mass Number: The total number of protons and neutrons in an atom (21 neutrons + 18 electrons = 39).
- Isotopes: Atoms with the same atomic number but different mass numbers due to different numbers of neutrons (e.g., 21 neutrons and 18 electrons can form two isotopes, one with 39 nucleons and one with 40 nucleons).
This element has 21 neutrons and 18 electrons - that’s a lot of particles! It’s like a mini universe in there. Whoa!
