To determine the number of valence electrons in the atom of an element A with atomic number 20 and to identify its valence shell, follow these steps:Step 1: Write the Electronic Configuration The atomic number of element A is 2
A valence electron is an electron that 'lives' in the last electron shell (or valence shell) of an atom. The atom will have one or more electron shells based on how many electrons the atom has. The very last shell that the atom has holds the valence electrons. The number of valence ...
Sodium (Na) Valence shell is not full. It takes less energy to give away 1 electron than “steal” 7 more. Alkaline Earth Metals (Group 2) Be, Mg, Ca, Sr, Ba, Ra How many valence electrons do they have? Are they still considered “reactive”? WHY? Are they more/less reactive tha...
Valence describes how easily anatomorradicalcan combine with other chemical species. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. Valence is denoted using a positive or negative integer used to represent this binding cap...
Hint: It has one electron!First Element of the Periodic Table:The periodic table is a table in which the chemical elements are arranged by atomic number. It starts with the element with the lowest atomic number all the way to the element with the highest atomic number, Oganesso...
