The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
Smaller
Iodine is a non metal element. Atomic mass number of it is 127.
The atomic mass of iodine is about 126.9 g/mol, which is indeed less than the atomic mass of many other elements. This low atomic mass for iodine is due to its position in the periodic table and the number of protons and neutrons in its nucleus.
Ni (Nickel) has a larger atomic size than Fe (Iron). This is because Nickel has more electrons and energy levels, which leads to a greater atomic radius compared to Iron. Additionally, Nickel is located in the same period as Iron on the periodic table, but it is to the right of Iron, indicating a larger atomic size.
In terms of atomic radius yes, nitrogen is larger than fluorine. However, the common fluorine isotopes have a greater mass than those of nitrogen.
The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.
Smaller
Iodine's electron configuration is 2, 8, 18, 18, 7; bromine's is 2, 8, 18, 7. At the simplest level of modelling there is one more electron shell occupying space in an iodine atom than in one of bromine.
Iodine is a non metal element. Atomic mass number of it is 127.
Bromine and iodine are denser than fluorine and chlorine due to their larger atomic sizes and greater atomic masses. The increase in size and mass of bromine and iodine atoms results in stronger van der Waals forces between the molecules, which leads to higher density.
Bromine has a SMALLER atomic radius because it has one more electron shell than Iodine. On the periodic table, atomic radius of an atom decreases across a period and increases down a group. Since Bromine and Iodine are in the same group, you know Bromine has a smaller atomic radius because it is in a lower period.
The atomic size of francium is of course greater.
Barium (Ba) is larger than Beryllium (Be) because as you move down a group on the periodic table, the atomic size increases. Barium is in a lower group than Beryllium and therefore has a larger atomic size.
The atomic mass of iodine is about 126.9 g/mol, which is indeed less than the atomic mass of many other elements. This low atomic mass for iodine is due to its position in the periodic table and the number of protons and neutrons in its nucleus.
Yes, osmium is a heavier element than iodine. Osmium has an atomic number of 76 and a higher atomic weight than iodine, which has an atomic number of 53.
Bromine's atomic radii is larger than that of chlorine.
Ni (Nickel) has a larger atomic size than Fe (Iron). This is because Nickel has more electrons and energy levels, which leads to a greater atomic radius compared to Iron. Additionally, Nickel is located in the same period as Iron on the periodic table, but it is to the right of Iron, indicating a larger atomic size.
