because of atomim configration
Group-1 has largest atomic radius. It decreases across a period
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
The element with the largest atomic radius among boron, aluminum, gallium, and indium is indium. As you move down the group in the periodic table, atomic radius generally increases due to the addition of electron shells. Indium, being the lowest in this group, has the largest atomic radius.
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
Group-1 has largest atomic radius. It decreases across a period
NO
The atomic radius of manganese is about 127 picometers. In the periodic table, manganese has a smaller atomic radius compared to elements in the same period but larger than elements in the same group.
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
The element in group 1 with the smallest atomic radius is lithium, due to its higher nuclear charge compared to the other elements in the group (such as sodium and potassium). This higher nuclear charge attracts the electrons more strongly, leading to a smaller atomic radius.
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
The element in group 3A with the largest atomic radius is thallium (Tl). As you move down a group on the periodic table, the atomic radius tends to increase due to the addition of more electron shells. Thallium, being lower in the group, will have a larger atomic radius compared to other elements in group 3A.
The element with the largest atomic radius among boron, aluminum, gallium, and indium is indium. As you move down the group in the periodic table, atomic radius generally increases due to the addition of electron shells. Indium, being the lowest in this group, has the largest atomic radius.
Bromine has the largest atomic radius among fluorine, chlorine, and bromine. Atomic radius increases down a group on the periodic table, so bromine, located at the bottom, has the largest atomic radius of the three elements.
Sulfur has the largest atomic radius among sodium, aluminum, silicon, and sulfur. This is because atomic radius generally increases as you move down a group in the periodic table, and sulfur is located further down the group compared to the other elements listed.
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
The group of elements with members of the smallest atomic radii for a given period is the group of noble gases. Noble gases have the smallest atomic radii because they have a completely filled valence shell, which results in strong electron-electron repulsions and a smaller atomic size.
