Write the orbital notation for any element by using the information on the periodic table to determine the number of electrons in each orbital. Orbitals are represented by the letters s, p, d and f. More »

The orbital notation for the element beryllium is 1s(2), 2s(2), where the parentheses represent superscript. Orbital notation is a way of representing the electron configuration of an element. In terms of configuration, ... More »

The orbital configuration for carbon is 1s2 2s2 2p2. It has four valence electrons. Carbon exists in nature as graphite and diamonds, but it often combines with other elements, such as hydrogen and oxygen, in forming com... More »

An atom of chromium with no charge has a total of 24 electrons, as indicated by the element's atomic number on the periodic table of elements. The atom also holds 24 protons and 28 neutrons. More »

The Roman numerals on a periodic table of elements define the chemical group of the elements in that column and identify the number of valence electrons of each element. Group IA elements have one valence electron; group... More »

To find the number of electrons an element has, locate it on the periodic table of elements, find the atomic number, and note the number of protons; because atoms are naturally electrically neutral, the protons and elect... More »

The element with 27 electrons in an orbital diagram is cobalt. Cobalt has 27 protons, so it has 27 electrons. The 22 different isotopes of cobalt each have a different number of neutrons, with atomic numbers ranging from... More »
