the electrons on the last shell of an atom are called valency electrons.
Electrons farthest from nucleus are valence electrons. They are present in outermost orbit.
It's called a valence electron.
It's called a valence electron.
An electron that is loosely bound to its nucleus is called a free electron. These electrons are not tightly held by the nucleus and can be easily influenced by external forces, making them important in conducting electricity in materials.
Materials in which electrons are loosely bound are called conductors. Conductors have a high conductivity due to their ability to easily allow for the flow of electrons. Metals like copper and aluminum are examples of good conductors.
A valance electron.
The region between the nucleus and the electrons in an atom is called the electron cloud.
the layer of electrons surrounding the nucleus of an atom is called "shells"
In covalent chemical bonds sometimes the electrons are loosely called "covalent electrons" as they are localised.
The outermost electron shell is called the valence shell. It contains the most reactive electrons because these electrons are farthest from the nucleus and are more likely to interact with other atoms to form chemical bonds.
If you are talking about elements, they are electrons.
electrons orbit around the nucleus
