Artificial atoms comprised of shells of electrons, without a nucleus present, have been used in silicon as the building blocks for quantum computers. UNSW use flat electron shells from artificial ...

Sodium and chlorine, two highly reactive elements, combine to form the stable compound sodium chloride (ordinary table salt). Questions for Discussion Describe the electron configuration of sodium.

For example, the electron configuration of oxygen (O) is 1s 2 2s 2 2p 4, indicating it has 6 valence electrons. Role of Valence Electrons in Chemical Bonding The electrons in the outermost shell ...

Sodium, this neutral atom with a loosely-held outermost electron, is now in the presence of water. This isn't just the neutral H2O molecules, but the hydroxyl ions and the individual protons.

They have familiar names like lithium, sodium and potassium. And they all want to get rid of that single, lonely electron, any way they can. Resource Produced by: ...

Light elements such as alkali metal (lithium, sodium) or halogen (fluorine, chlorine) are present in various substances and indeed play significant roles in our life. Although atomic behaviours of ...
