Not all electrons are the same age, since there are a variety of processes by which subatomic particles can change into other particles (by reason either of decay, or high energy collision with other particles). However in general, electrons formed not long after the Big Bang which was a bit less than fourteen billion years ago.
Electrons are the subatomic particles that determine the reactivity of an element. The number of electrons in the outermost shell of an atom, known as valence electrons, determines how likely an atom is to form chemical bonds with other atoms.
The electrons in the outermost shell of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to create molecules. The number of valence electrons influences the reactivity and chemical properties of an element.
Outer energy level electrons, or valence electron.
Inner orbiting electrons are called core electrons. These are the electrons that are closest to the nucleus and are not involved in bonding or chemical reactions.
A fluorine atom has 9 electrons.
the answer is 24 electrons and yes im only 14 yrs old again
Yes, the "old" televisions use magnetism to controll the movements of the electrons.
You're thinking of electrons - but that's a very old (and erroneous) description.
Old (very old) tradition, when electricity was assumed to flow from positive to negative. (They hadn't figured out electrons yet.)
Electrons in the outermost shell are valence electrons!
the electrons in the outermost shell of an atom are considered to be the valence electrons.
anything containing loose electrons such as steel, copper, silver, gold, and good old water
It would have 2 electron shells because the first shell can only hold up to two electrons and the second shell will be responsible for the rest of them.
Lone-pair electrons, Bonded pairs of electrons
Valence electrons
8 electrons
A metalloid with 4 electrons, such as silicon, has 2 core electrons. In the case of silicon, the electron configuration is 1s² 2s² 2p², where the 1s² electrons are the core electrons, while the 2s² and 2p² electrons are considered valence electrons. Thus, it has 2 core electrons and 4 total electrons.
