As the number of electrons and protons are same but the number of neutrons are different, these atoms are isotopes of each other.

There are 10 protons, and 10 electrons in un-ionized neon. 90% of the neon atoms contain 10 neutrons. There are a few with 11 neutrons and around 9% with 12. Those with extra neutrons are called isotopes, the nucleii having 10 protons but a few with different numbers of neutrons.

Answer. they are known as isotopes.

Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Researchers from the University of Alberta in and the National Institute for Nanotechnology in Canada created the sharpest object ever made. The new nano object is tungsten needle tapering down to about the thickness of single atom.

Damascus Steel sword

Obsidian

Good quality obsidian fractures down to single molecules which can produce a cutting edge 500 times sharper than the sharpest steel scalpel blade (“American Medical News”, Nov. 2, 1984:21). On the cellular level an obsidian knife can cut between cells rather than tear the cells as a steel knife will do.

Yes, you can use a utility knife to score glass so you can snap it along the cut and break it evenly. Use a straight edge or a ruler to guide your utility knife and score a straight line into the surface of the glass.

No, a glass cutter is not a knife. You should use a razor blade so the silver film on the back side of the mirror will be as clean as the glass cut. You cannot cut the mirror on the film side with the glass cutter as it will not score the glass; you will ruin the mirror every time.

Time to Score—Wearing your goggles and gloves, use your cutting tool and a straightedge to score the mirror according to your measurements. Remember, too much pressure may cause you to break the mirror, and too little will not score the surface as desired. Carefully break off pieces of the mirror.
