This chemical element is calcium (Ca).
There is a sea of delocalised electrons formed in a metallic element, and the ions are attrracted to this.
The electron shell arrangement of Ceasium is 2.8.8.18.18.1
to have a full outer orbital like neon, it will have to bond with another element.
No. A Hydrogen atom has 1 proton and 1 electron with the electron arrangement 1. An Oxygen atom has 8 protons, 8 neutrons and 8 electrons with the elecron arrangement 2. 6.
Chlorine
This chemical element is calcium (Ca).
Chlorine

All of the elements in Period 3, excluding group 18/VIIIA, have the same inside electron arrangement as phosphorus. They all have the electron configuration of neon as their inside arrangement of electrons.
All of the elements in Period 3, excluding group 18/VIIIA, have the same inside electron arrangement as phosphorus. They all have the electron configuration of neon as their inside arrangement of electrons.
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
because different element have different number of electrons.
The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons
The electron configuration, in standard form, is [Kr] 4d10 5s2 5p6.
No element has the exact same election arrangement as another element. However ion can have the same election arrangement as another element. For example Chloride (Cl-) has the same configuration as Argon, and Potassium (I) (K+) also has the same configuration as argon.
The electron shell arrangement of Ceasium is 2.8.8.18.18.1
