Each sublevel has differing numbers of orbitals. Sublevels are designated with lower-case letters. Sublevel s contains one orbital, p contains three, d has five, f has seven, g has nine, h has 11 and i has 13.Know More
The periodic table of elements contains seven rows; therefore, elements can have up to seven energy levels, depending on how many electrons the element possess. Electrons travel around the atom in orbitals. Each orbital houses a maximum of two electrons.
With each subsequent energy level, another sublevel is added. Energy level one contains only one sublevel, the s with its one orbital. Energy level 2 contains s and p sublevels, so this energy level has a total of four orbitals. Energy level 3 has s, p and d sublevels; therefore, this energy level has a total of nine orbitals.Learn more about Atoms & Molecules
Hexane can form five isomers with its six carbon bonds. The five isomers are 2-methylpentane, 3-methylpentane, 2,2-dimethylbutane, 2,3-dimethylbutane and hexane itself, which is a straight chain of six carbon atoms.Full Answer >
The chemical element iodine has exactly 53 protons. The element also has 53 electrons, since all atoms have the same number of protons as they do electrons in order to make the atom neutral.Full Answer >
A nitrogen atom contains seven protons. This is true of all isotopes of nitrogen; radioactive isotopes of the element vary only in their number of neutrons.Full Answer >
As of 2014, there are 118 elements on the periodic chart.91 of these are generally in the list of naturally occurring elements, with atomic numbers 1 to 92. Technetium, element number 43, is radioactive with a very short half-life, so scientists initially did not believe it occurred naturally; such beliefs have since been refuted. About.com reports there are 98 naturally occurring elements.Full Answer >
