<em>Proton</em>
<em>Neutron </em>
<em>Electron </em>
- Surrounding the nucleus in orbitals
Two (protons and neutrons) of the three particles are found in the nucleus of an atom. <u>Electrons</u> are not, they are surrounding the nucleus.
Why does the chemical reaction seen here obey the law of conservation of matter?
<u><em>Answer:</em></u>
- Because there are the same number of atoms of each element shown on both sides
<u><em>Explanation</em></u>
- As in chemical reactions, atoms bonds are break and new bonds are formed. As new substance are formed but overall they have same elements, no new elements come from outside or go to outside. In other words , rearrangement of atoms take place but number of atoms remained same.
NaOH + HCl -----> NaCl + H2O
- As in above reaction there are the same number of atoms of each element shown on both sides .
