The key  characteristic  of oxidation-  reduction   reaction  is electrons   are  exchanged  ( answer  C)

   <u><em>Explanation</em></u>

  • Oxidation-reduction   reaction  is type  of reaction  that involve a transfer  of electrons  between two  species.

Example  of oxidation - reduction  reaction is

  CH4  +2O2 →   CO2  + 2H2O

  from reaction above C  atom  is oxidized  from  oxidation state -4  to 4.

   On the  other hand O atoms   are reduced  from oxidation state of 0 to  2-.  therefore   there is exchange  of electrons  between  C atoms  and O atoms.

The number of positive changes in the nucleus of an atom is equal to
raketka [301]

Answer:

The number of positive charges in nucleus of an atoms are equal to the atomic number and also positive charges are equal to the negative charges which are electrons in neutral atom.

Explanation:

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

Electron:

The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.

Symbol= e⁻

Mass= 9.10938356×10⁻³¹ Kg

It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.

Neutron and proton:

Neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.

Symbol of proton= P⁺

Symbol of neutron= n⁰

Mass of proton=1.672623×10⁻²⁷ Kg

Mass of neutron=1.674929×10⁻²⁷ Kg

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

For example

The carbon have six protons and six neutrons so its atomic mass is 12 amu and atomic number is six.
