Atomic nucleus

A community portal about Atomic nucleus with blogs, videos, and photos. According to Wikipedia.org: The nucleus of an atom is the very dense region in its centre consisting of protons and neutrons. The size of the nucleus is in the range 1.5 to 15 fm, much smaller than the size of the atom itself, and almost all of the mass in an atom is made up from the protons and neutrons with almost no contribution from the electrons.

Atoms: Protons, Neutrons and Electrons, OH My!

We're learning about atoms. We built our own carbon atom on the wall with plastic balls and velcro. We wrote "nucleus" on the nucleus and used sticky note tabs for protons and neutrons. The other balls are the electrons orbiting the nucleus. We can remove the protons, neutrons and electrons and create atoms of helium or hydrogen, too.

Graphene Atomic-Scale Balance

Graphene resonator is one atom thick. 'Physicists in the US claim to have made the world's thinnest resonators using sheets of carbon as little as one atomic layer thick. Paul McEuen and colleagues at Cornell University suspended graphene sheets over micrometre-sized trenches to create devices that vibrate at their own natural frequencies. According to McEuen, the resonators could be used to create highly-sensitive mass and force detectors (Science 315 490).' Wikipedia: Graphene. 'Graphene... Read Full Story

What Does CO2 Gas Weigh?

Written by

From: nuclearenergycansaveus.blogspot.com

The weight of the CO2 molecule is the combined weight of one carbon, and two oxygen atoms. Each atom's weight depends on the number of nucleotides, protons and neutrons, in its nucleus. The carbon atom is atomic number 6, meaning 6 protons in the nucleus. Carbon has an atomic weight of 12, with six protons and six neutrons (neutral particles) in the nucleus. Likewise oxygen is atomic number 8, and atomic weight 16; 16 particles in the nucleus.When a carbon atom burns, it is oxidized by oxygen... Read Full Story
