Elements with a smaller atomic radius than strontium include beryllium, magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and argon. Generally, atomic radius decreases across a period from left to right due to increased nuclear charge, which pulls electrons closer to the nucleus. Additionally, atomic radius increases down a group, so elements above strontium in the same group have smaller radii.

What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.
Which element in each pair has atoms with a larger atomic radius selenium oxygen?
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
What elements is the smallest Ca Mg Be Sr?
Among the elements listed—calcium (Ca), magnesium (Mg), beryllium (Be), and strontium (Sr)—beryllium (Be) is the smallest in terms of atomic size. This is because beryllium is higher up in the periodic table, with fewer electron shells compared to the other elements, resulting in a smaller atomic radius.
What has greater atomic size calcium or strontium?
Strontium has a greater atomic size than calcium because strontium has more electrons and energy levels in its electron cloud, resulting in a larger atomic radius.
Which element has a larger atomic radius strontium or magnesium?
Strontium: At least within periodic table columns that do not include transition metals, an element with higher atomic number always has a larger atomic radius. This principle is generally correct also for columns that do include transition metals, but in an important exception, hafnium has almost the same atomic radius as zirconium, making the separation of these two metals very difficult by chemical means.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
What is the atomic radius of gallium and how does it compare to other elements in the periodic table?
The atomic radius of gallium is about 135 picometers. In the periodic table, gallium has a larger atomic radius compared to elements to its left and a smaller atomic radius compared to elements to its right.
What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.
What is the atomic radius of manganese and how does it compare to other elements in the periodic table?
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.
Which element in each pair has atoms with a larger atomic radius selenium oxygen?
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
Which element in each pair has atoms with a larger atomic radius strontium or magnesium?
Strontium
What elements is the smallest Ca Mg Be Sr?
Among the elements listed—calcium (Ca), magnesium (Mg), beryllium (Be), and strontium (Sr)—beryllium (Be) is the smallest in terms of atomic size. This is because beryllium is higher up in the periodic table, with fewer electron shells compared to the other elements, resulting in a smaller atomic radius.
What is smaller than the atomic radius of Oxygen?
The atomic radius of oxygen is about 60 picometers. Therefore, atoms of elements such as hydrogen (25 picometers) and helium (31 picometers) have smaller atomic radii than oxygen.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
How does fluorines atomic radius compare to oxygen radius and chlorines radius?
Fluorine has the smallest atomic radius among fluorine, oxygen, and chlorine. Oxygen has a larger atomic radius than fluorine but smaller than chlorine. Chlorine has the largest atomic radius among the three elements.
What has greater atomic size calcium or strontium?
Strontium has a greater atomic size than calcium because strontium has more electrons and energy levels in its electron cloud, resulting in a larger atomic radius.
