Answer:
Ca
Explanation:
As a general trend on the periodic table, the electronegativities of elements decrease down the group and increase across the periods. Since calcium is in group two , it is expected to have the lowest amount of electronegativity due to its specific location on the periodic table.
To show that this prediction is true, I will write the elecronegativity values of these atoms. Calcium has a value 1.0, Silver 1.93 , Iron 1.83 and chromium 1.66
Answer:
Dalton's says atoms of different elements differ in size and mass, whereas the modern theory says they differ in average mass. Dalton's says atoms are individual particles, whereas the modern theory says atoms are divisible into subatomic particles like protons, neutrons, and electrons..

Remember Tin isn’t Ti, it’s actually Sn and by looking at the periodic table you find it is 118.7 g
