The metals will generally have one, two or three electrons in their outer shell, which are known as valence electrons. Most atoms want eight valence...Become a member and unlock all Study Answers Start today. Tr
How many valence electrons (electrons in the outer energy level) does oxygen have?Classification of Oxygen:Oxygen is a non-metal element found in Group 16 of the periodic table. It is a gas in it's standard state and is the element that we breathe in when we inhale using ...
Ambient light - Ambient light is light that has bounced and scattered in many directions so that it is does not seem to have a specific source. A good example of ambient light is the glow in the sky around a major city. It would be very hard to identify a single source of light for...

Electrons Can Move The protons and neutrons in the nucleus are held together very tightly. Normally the nucleus does not change. But some of the outer electrons are held very loosely. They can move from one atom to another. An atom that loses electrons has more positive charges (protons) ...
When we switch on the power, the copper sulfate solution splits into ions (atoms with too few or too many electrons). Copper ions (which are positively charged) are attracted to the negatively charged brass electrode and slowly deposit on it—producing a thin later of copper plate. Meanwhile...
Real-time social media reports: Many aurora chasers post live updates on platforms like X (formerly Twitter). I have been fortunate enough to witness the northern lights throughout Norway and Sweden, but I have to say the most dramatic and colorful display was viewed from my own backyard in...

increased temperature. The electrons "jump" from their ground state to a higher energy level. As they return to their ground state, they emit visible light. The color of the light is connected to the location of the electrons and the affinity the outer-shell electrons have to the atomic ...
