Alpha (α), beta (β-) and gamma (γ) decay. When the nucleus of an atom possesses either too many or too few neutrons compared to the number of protons it becomes unstable. These are called radioactive isotopes. Unstable nuclei split up in a process called radioactive decay and emit radioactive radiation.
Formula of sodium phosphate = Na₃PO₄
So, one mole of sodium phosphate molecules have 3 moles of Na atoms
Then, 1.6 moles of Na₃PO₄ will have: 1.6 × 3 = 4.8 moles of sodium atoms will be present
When water evaporates (which involves breaking of hydrogen bonds), it removes energy from its surroundings in a fashion that renders water an Excellent coolant.
Within water molecules, polar covalent connections are created between the hydrogen and oxygen atoms. The shared electrons are attached to the oxygen atom for a longer period of time than they are to the hydrogen atoms. A water molecule has no overall charge, but each hydrogen atom has a little positive charge, and each oxygen atom has a slight negative charge. The slightly positive hydrogen atoms repel one another and form the distinctive shape as a result of these charges. The positive and negative charges in the various regions of each water molecule cause them to attract other water molecules. Additionally, water forms hydrogen bonds with other polar molecules (like sugars) by attraction.

Atomic mass of Au = 196.9 g/mole
<span>it means that 1 mole of Au = 196.9 g </span>
<span>so 3.5 moles of Au = 196.9 X 3.5 = 689.15 g</span>
