The answer is D: Electrons ;)
Physics (static electricity)
electron is the - circles around the atom, protons are the + circles inside the atom, neutrons are the blank circles inside the atom
Electrons have negative charge ( - ) and also rotate around the atom - they are not in the nucleus
Protons are in the nucleus but have a positive charge ( + )
neutrons have no charge and are in the nucleus
Sometime u feel shock when u touch any current containing wire.. This is due to static discharge (flow of electrons)
12 protons, 12 neutrons, 10 electrons
There are 12 protons from the magnesium atom.
In the ionosphere, the collision that raises the energy levels of oxygen and nitrogen occurs between:gas atomselectrons
Earth's uppermost layer is ionized and it is known as ionosphere. In altitude, ionosphere is about 60 km to 1,000 km high.
It is ionized by solar radiations and in atmospheric electricity ionosphere plays an important role as inner edge of magnetosphere is formed by ionosphere.
Also, in the ionosphere, the collision that raises the energy levels of oxygen and nitrogen occurs between gas atoms and electrons.
