Answer:
Ca has 20 protons, so neutral it would have 20 electrons, but according to the charge, 2 electrons have been lost.
Explanation:
There is an uneven distribution of electrons between oxygen & hydrogen atoms
Answer: Liver
Glucose is the most important fuel source for the body, specifically the brain. It is absorbed through the
mucosal lining into the epithelial cells of the intestine by active transport
via sodium-dependent hexose
transporter. From the epithelial cells, glucose is moved into the surrounding capillaries
by facilitated diffusion into the liver. Once in the liver, glucose is stored as glycogen.
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.
<span>In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons

It is the nucleus that contains DNA and controls the functions of the cells
