They are lost.
They are the electrons in the (outer) valence shell
Valence electrons are electrons on the outermost "level". And depending on its electron configuration, it plays a role in which if the atom requires to gain or lose electrons in order to become "stable", it can accept or give electrons to another atom in a chemical reaction.
The number specified is called the "valence" of the atom for the particular reaction occurring. (Some elements have more than one possible valence.)
Some or all of its valence electrons.
In general chemical reactions, metals tend to loose electrons and non-metals gain electrons. The no. of electrons loosed by metals is the same as the no. of electrons gained by the non-metals.
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
broken and recreated or mixed with other chemicals
They are the electrons in the (outer) valence shell
Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
during a chemical reaction valence electrons are most always transferred

Yes. If there are 1 to 3 valence electrons in an atom, then generally those elements will lose these electrons to attain noble gas configuration. If there are 5 to 7 valence electrons, then generally those elements will gain electrons to attain noble gas configuration.
Yes, it is correct.
Some or all of its valence electrons.
Chemical bonding only involves the outermost level of electrons, valence electrons. The actual reaction takes place far away from the nucleus of the atom where the protons are. There are reactions that involve the protons, though, but they are nuclear reactions, not chemical reactions. They are usually achieved through high-speed collision in labs.
Elements on the periodic table in the same group have the same number of valence electrons. Since valence electrons are the only part of an atom that interacts with other atoms during a chemical reaction, you can make generalizations about elements' reactivity based upon what group they're in. Elements in the same group will behave similarly in chemical reactions even if they bear little resemblance to each other physically.
