Smaller
Yes, strontium is larger than a calcium atom. Strontium has a higher atomic number (38) compared to calcium (20), which means it has more electron shells. This additional shell increases the size of the strontium atom, resulting in a larger atomic radius than that of calcium.
An iodine atom has one more principal energy level than a bromine atom. Therefore the radius of an iodine atom is greater than the latter.
Atomic (covalent) radius of hydrogen is 31 pm. Atomic (covalent) radius of gold is 136 pm.
The positive ion lost an electron.

Iodine is the largest atom among bromine, fluorine, iodine, and chlorine. It has more electron shells and a larger atomic radius compared to the other three elements.
Iodine is a bigger atom than chlorine because it has more electrons and atomic radius.
The smallest radius from I Br Br I would be the bromine atom since it is closer to the central iodine atom compared to the outer iodine atom.
Iodine is the biggest atom among bromine, fluorine, chlorine and iodine as it has the highest atomic number and atomic radius.
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.
An element that has a larger ionic radius than calcium is strontium. Strontium is located below calcium in the same group of the periodic table, which means it has an extra energy level and therefore a larger ionic radius.
Atomic (covalent) radius of hydrogen is 31 pm. Atomic (covalent) radius of gold is 136 pm.
The atomic radius of an atom generally increases as you move down a group in the periodic table due to the addition of more electron shells. Iodine is located below fluorine in the same group (Group 17), so iodine has more electron shells compared to fluorine, leading to a larger atomic radius.
No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.
