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.

Which subatomic particle determines reactivity?
Electrons, for chemical reactions
What are the electrons in the outer shell?
Those electrons are the valence electrons. They are the electrons which mostly take part in exchange of electrons or sharing of electrons. Hence, valence shell electrons are a very important part of chemistry since all the reactions due to them only.
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
How many valence electrons are found in a krypton atom?
There are 8 Valence Electrons.
Can chemical bonds be produced by losing electrons losing nuetrons transferring electrons sharing electrons or gaining electrons?
Chemical bonds can be only produced by gaining, losing or sharing electrons. If a compound is formed by losing or gaining electrons, it is called an ionic bond and if by sharing electrons, it is called a covalent bond.
How many electrons does one atom of chromium have?
the answer is 24 electrons and yes im only 14 yrs old again
Does a television use magnetism?
Yes, the "old" televisions use magnetism to controll the movements of the electrons.
What is the area outside the nucleus where electrons are found?
what is the area outside the nucleus where electrons are found
Which part of the atom moves arround the nucleus?
You're thinking of electrons - but that's a very old (and erroneous) description.
Which subatomic particle determines reactivity?
Electrons, for chemical reactions
What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
Why positive charges are called sources and negative are called sink?
Old (very old) tradition, when electricity was assumed to flow from positive to negative. (They hadn't figured out electrons yet.)
What is another name for outermost electrons?
Electrons in the outermost shell are valence electrons!
Whuch of the following are classified as an electron group?
Lone-pair electrons, Bonded pairs of electrons
The outermost electrons in an atom are called?
Valence electrons
What part of an atom forms a chemical bond?
The electrons (especially the valence electrons)
How many numbers of electrons does electrons have?
8 electrons
