Because atoms are conserved in a reaction and atoms are the building blocks of matter thus is it said that matter is conserved.
for your own knowledge .... a few other things are conserved

Answer:
The correct option is: A carbon atom can complete its valence shell by forming four covalent bonds
Explanation:
Carbon is a chemical element that belongs to the group 14 of the periodic table. The atomic number of carbon atom is 6 and it is denoted by the chemical symbol C.
The electronic configuration of carbon is: 1s², 2s², 2p².
Therefore, there are 2 electrons in the first electronic shell and 4 electrons in the second electronic shell of the carbon atom.
<u>There are </u><u>four valence electrons </u><u>in a carbon atom and thus it can form four covalent bonds to complete its valence shell. Therefore, carbon atom is tetravalent.</u>
