What else can I help you with?
An electron that is found in the outermost shell of an atom and that determines the atoms chemical properties?
This electron is a valance electron.
What is an atom that has gained or lost electrons and is no longer neutral?
Valance electron
What type of bond is it when one atom gains or loses a valance electron from a different atom?
metallic bond
What is meant by valency orbit and valency electron?
A valance electron is one that is associated with an atom. The valence orbit is the one that electron travels in.
When an atom gains or loses a valance electron does it have a physical or chemical change?
That is a chemical change.
What makes up an atom and how do they bond?
An atom is a nucleolus and an associated electron cloud. They bond by swapping OR sharing (valance or outer) electrons.
What is an core electron?
A core electron is an electron in an atom that is not easily removed or involved in chemical reactions. Core electrons occupy the inner energy levels of an atom and are tightly bound to the nucleus. They play a crucial role in determining the atom's chemical properties.
How many valence electrons does an atom of any halogen have?
A halogen is located in group 17 of the periodic table, so the electron configuration for the valance electron would be ns2np5 (n=energy level). So all halogens have 7 valance electrons.
Were is the electron located?
In an Atom!
Where is a electron cloud located?
The electron cloud in an atom is located outside of the nucleus.
Is a electron located inside the nucleus of an atom?
No, they are located in the shells or orbits of an atom.
How many valance electrons in B?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
