how many electrons are there in the third orbit of potassium?
478015
The 3rd shell of any atom can actually contain 18 electrons, but potassium (K) normally has only one electron in the 4s orbital.

Krypton has an atomic number 36, so it has 36 electrons. Bromine with an atomic number of 35 acquires one electron to attain 36 electrons. This makes it isoelectronic with krypton. The anion of bromine is Br-.

Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals. The fourth and higher levels also have an f sublevel, containing seven f orbitals, which can hold a maximum of 14 electrons.

There are 3×2p orbitals, px , py , and pz , which are oriented along the Cartesian axes. Each p orbital can accommodate 2 electrons, and thus there can be 6 electrons in the 2p sublevel.

K is the symbol for potassium, and the number of valence electron can be found through its' group on the periodic table. Hence, it has one valence electron.

X atom (means no radical) having 19 electrons will be sure potassium, according to the defination of atomic number. Now, the the valancy of an element is equivalent to the number of electrons present in its outermost shell.

Answer and Explanation: Eighteen electrons can have the designation n = 3. There is 3s, 3p, and 3d orbitals. The s orbital can hold 2 electrons.

Potassium (K) has 19 total electrons, as indicated by its atomic number (the number of electrons equals the number of protons in a neutral atom).

Therefore the Potassium electron configuration will be 1s22s22p63s23p64s1. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

phosphorus has three electrons in its 3p sub level.

The number of valence electrons corresponds to the group number the element is in. In the case of potassium, it is a group 1 element and is part of the alkali metals. This means that potassium will have 1 valence electron.
