F.isobars - a line drawn on a weather map connecting points of equal pressure is called isobars.

example.. argon 40

potassium 40

.two differences between isobars and isotopes.

isobars are those elements which have different atomic number but the same mass number. while isotopes are those elements having the same atomic number and different mass number..

two uses of isotopes.

uranium 235 - for nuclear fission and as fuel in unclear reactors.

# an isotope cobalt - used In the treatment for cancer

# an isotope iodine - used in treatment of goiter.

The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

<h3>What are organs?</h3>

Organs are a collection of tissues that are closely related and which perform a related function.

The role and function of the organs of the digestive system are as follows:

  • Pancreas - produces pancreatic juice which contain digestive enzymes
  • Liver - produces bile for the emulsification of fat
  • Stomach - serves as a temporary store of food and produces digestive juices
  • Small intestine - functions in food digestion
  • Large Intestine - helps to remove undigested food from the body

Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

Based on Reference Table S, the atoms of which of these elements have the strongest attraction for electrons in a chemical bond?
BabaBlast [244]
Answer is (1) - N

<em>Explanation:</em>

I think the given chart is electronegativity chart.

Electronegativity is a value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is high, then the attraction to the electrons is high unless the attraction to the electrons is low. </u>

Electronegativity increases from left to right of the periodic table and decreases from up to down. 
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).

The electronegativity values for given atoms are
  N - 3.0
  Na - 0.9
  P - 2.1
  Pt - 2.2 </span>
