An atom of gold is bigger and heavier. Split it open and you'll find 79 protons and 118 neutrons in the nucleus and 79 electrons spinning round the edge. The protons, neutrons, and electrons in the atoms of iron and gold are identical—there are just different numbers of them. In ...
Some of them make it into our upper atmosphere, where they collide with atoms—with oxygen and nitrogen atoms. This collision causes the atoms to light up, to glow… different types of atoms glowing different colors. And this is what’s happening when we’re seeing an aurora.Now let’s ...
Which intermolecular force is present in all molecules and atoms? What kind of intermolecular forces exists in sand? What are the intermolecular forces of protactinium? What kind of intermolecular force is there between sand molecules? A) What are ion-dipole intermolecular forces? ...
There is also such a thing asantimatter, which is not the same as dark matter. Antimatter consists of particles that are essentially the same as visible matter particles but with opposite electrical charges. These particles are called antiprotons and positrons (or antielectrons). When antiparticl...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
What are the Group I ions? Why do atoms of the same group form ions of the same charge? (a) They have the same number of valence electrons (b) They have the same number of protons (c) They have the same number of electrons (d) They have the same number of valence neutr...

What is the arrangement of atoms within a molecule called? Molecules: Atoms are the individual components that make up every substance. Molecules are composed of two or more atoms and molecules are the basis for every chemical compound. The way that atoms are arranged within a molecule differs ...
elementary (electrons) or composite (protons and neutrons) in nature. This means that electrons have no known internal structure, whereas protons and neutrons are made up of other subatomic particles. called quarks. There are two types of quarks in atoms, which have a fractional electric charge....
Found in thousands of electronic products, a semiconductor is a material that conducts electricity more than an insulator but less than a pure conductor. There are four basic types of semiconductors. The semiconductor industry is focused on developing products with three traits as goals: smaller, fa...
