The element produced by this nuclear reaction, I believe would be a metal.
Electrons are negatively charged. If you remove negative particles, the leftover atom is positive and positive is really just another word for "less negative".
Answer:
Reduction
Explanation:
Oxidation is a process that involves loss of electrons.
Reduction is a process that involves gain of electrons.
In this equation, the electrons (4e-) are in the reactant side. This means that it is gain of electrons.
The reaction is a reduction reaction.
Answer:
2 pairs (4 electrons)
Explanation:
In a molecule of oxygen there are 2 oxygen atoms. There are 6 electrons in the outer shells of oxygen atoms. When 2 oxygen atoms form a covalent bond they share their electrons. In a diagram this would be represented by the overlap of the two circles representing the outer shells of both oxygen atoms. If each oxygen atom 'puts forward' 2 electrons into the centre, then 4 will be shared overall for each atom, making both atoms have full outer shells of 8 electrons each. 4 electrons make 2 pairs, hence the answer.
