The electron configuration for gallium is 1s22s22p6<3s23p63d104s24p1, according to the Thomas Jefferson National Accelerator Facility Office of Science Education. Gallium is a metallic element with an atomic weight of 69.723 amu.Continue Reading
A neutral atom of gallium has 31 electrons. The negative charge of each electron cancels out the positive charges of the 31 protons, giving a neutral gallium atom a net charge of zero.
Gallium's electron configuration shows how these 31 electrons are arranged. One atom of gallium has two electrons in the first energy level, eight in the second energy level, 18 in the third energy level and three in the fourth energy level.
The 4s2 and 4p1 parts of the configuration show how many valence electrons are in a gallium atom. The outer shell has a total of three electrons -- two in the s orbital and one in the p orbital. This means the atom has three valence electrons.
Gallium is found in thermometers that are used to measure high temperatures. The element is also used to create metal alloys and produce transistors. Gallium is in group 13 and period four of the Periodic Table of the Elements. Groups are the vertical columns of the table, while periods are the horizontal rows. At room temperature, gallium is a solid.Learn more about Atoms & Molecules
To make an electron configuration list, first find the atomic number, then count up the number of electrons and list them in the appropriate energy level and orbital. The information to write an electron configuration is typically available by locating the element on the periodic table. For example, the electron configuration of nitrogen is 1s2 2s2 2p3.Full Answer >
Potassium has an electron configuration of 1s22s22p63s23p64s1. The noble gas configuration of this element is [Ar] 4s1. The [Ar] in this configuration represents the electron configuration for argon.Full Answer >
A condensed electron configuration is also known as noble gas notation because it uses the last noble gas of the row above the row containing the element being notated to shorten the electron notation for the element. Condensed electron configuration relies upon the same shorthand as regular electron notation.Full Answer >
Silicon has an electron configuration of 1s2 2s2 2p6 3s2 3p2. Using the noble gas notation, the electron configuration of silicon can be denoted by Ne 3s2 3p2.Full Answer >
