The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
Potassium is larger than magnesium because potassium has one more electron shell than magnesium, leading to a larger atomic size. Additionally, the increase in nuclear charge from magnesium to potassium is not enough to offset the added electron shell, resulting in a larger atomic radius for potassium.
Calcium's atomice weight is 40.078 amu (atomic mass units).
Potassium has a larger atomic radius compared to bromine. This is because atomic radius generally increases as you move down a group in the periodic table, and potassium is located in a lower group (Group 1) compared to bromine (Group 17).
Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
The atomic radius of calcium is about 197 picometers (pm).
Potassium is larger than magnesium because potassium has one more electron shell than magnesium, leading to a larger atomic size. Additionally, the increase in nuclear charge from magnesium to potassium is not enough to offset the added electron shell, resulting in a larger atomic radius for potassium.
Calcium's atomice weight is 40.078 amu (atomic mass units).
POTASSIUM: Potassium is a chemical element. It has the symbol K and atomic number 19. MAGNESIUM: Magnesium is a chemical element with the symbol Mg, the atomic number 12, and an atomic mass of 24.31. Magnesium is the ninth most abundant element in the Earth by mass. It constitutes about 2% of the Earth's crust by mass, and it is the third most abundant element dissolved in seawater.
Mg: 24.305 K: 39.0983

Calcium has a larger atomic radius than magnesium and a smaller atomic radius than potassium. This trend is due to the increase in number of protons and electrons as you move across the period on the periodic table from magnesium to calcium to potassium.
The atomic radius of calcium is about 197 picometers (pm).
The atomic radius of sodium (Na) is smaller than the atomic radius of potassium (K). Sodium has a smaller atomic radius because it has fewer electron shells compared to potassium.
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
50g of magnesium has more atoms because magnesium has a higher atomic mass compared to lithium.
Calcium is a metal element. Atomic mass of it is 40.
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.
