Interpretation:
The atom of an element has
Concept introduction Electron dot structure for an atom is the structure which denotes the valence electrons around the elements.
Answer to Problem 27PP
The name of the element is Aluminum.
There are THREE valence electrons are shown its electron dot structure.
Explanation of Solution
Given: Atom of an element has
Explanations:
The number of electron indicates that the given element has
Thus,
The atomic number of the element is
So, its electronic configuration is
From electron configuration now it’s clear that there are three valence electrons. Thus, there are 3 electrons represented in electron dot structure as electron dot structure for an atom is a representation of the valence shell electrons in an atom.
Thus,
The name of the element is Aluminum
There are three valence electrons are shown its electron dot structure.
