Noble gas
An atom's atomic number tells us its number of protons and electrons. Checking the Periodic Table for the element having an atomic number of 18, we find that it is argon. Argon's electron configuration is 1s2 2s2 2p6 3s2 3p6, which has all of its energy levels filled.

∙ 13y agoIn reference to the valence electron configuration - 2, 8, 18 ect..?
A noble gas. Found at the very right of the periodic table
Wiki User
∙ 13y agothey are called transition metals
hope this helped!

What is the electron configuration of Li and F?
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
What is the correct electron configuration for an element with 5 electrons in the 3d energy sublevel?
1s22s22p63s23p64s23d5
What is the valence electron configuration for the phosphorus atom?
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.
What is the term for the shorthand description of the arrangement of electrons by sublevels according to increasing energy?

How many valance electrons are there in Fr plus?
Fr is in the 1st period. It removes an electron to get noble gas configuration. Fr+ does not have valence electrons.Francium has 1 electron in its outermost energy level. It donates its outermost electron to stabilize its electron configuration. Francium(I) has no valence electrons.
What is the set of numbers that shows the arrangement of electrons in their shells?
The set of numbers that shows the arrangement of electrons in their shells is known as the electron configuration. It is based on the principle that electrons fill the lowest energy levels first before moving to higher energy levels. The electron configuration is typically represented by a series of numbers and letters indicating the number of electrons in each energy level and orbital.
Why does sodium have electrons that are not arranged in its energy levels?
Sodium atoms do have electrons that are arranged in energy levels. The electron configuration of sodium is 1s22s22p63s1.

What is the number for electrons on hydrogen's first energy level?
Hydrogen's electron configuration is 1s1. It has only one electron. It is located in the first energy level.
What is the electron configuration of an element?
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
