How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
Why does Fr have the largest atomic radius?
Many energy levels of electrons and low effective nuclear charge/low Coulombic force.
Is He the largest atomic size out of Li or Fr?
Fr (Francium) has the largest atomic size compared to Li (Lithium) because Francium is located at the bottom of group 1 on the periodic table, which means it has more energy levels and electron shells compared to Lithium, hence larger atomic size.
What is the daughter element produced from the alpha decay of 217 87 fr?
The daughter element produced from the alpha decay of ^217_87 Fr is ^213_85 At (Astatine). In alpha decay, the parent atom loses an alpha particle (two protons and two neutrons), resulting in the transformation into a new element with a lower atomic number.
What is the atomic number of francium?
The atomic number of francium (Fr) is 87.The atomic weight of Fr is 223 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
Which is larger a hydrogen H atom or a francium Fr atom?
A francium atom (Fr) is larger than a hydrogen atom (H) due to the increase in number of protons and electrons, resulting in larger atomic size. Francium has more electron shells compared to hydrogen, leading to a greater atomic radius.
What element has an atomic radius of 97 pm?
The element with an atomic radius of 97 pm is Francium (Fr). Francium has a large atomic radius due to its location in the alkali metal group, which generally have larger atomic radii.
What naturally occuring element has the largest atom?
Cs, cesium: atomic radius is 0.265 phttp://wiki.answers.com/wiki/Picometre.(However: Fr is the biggest with 0.265 nm, but naturally occuring only in extremely traces).
Which of the following has the smallest atomic radius P AL S Si Cl?
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
How does the atomic radius change from top to bottom in a group 1 and 2 in the periodic table?
Going down and to the left on the periodic table, atomic radius increases. Therefore, the smallest atomic radius is that of Helium (He), and the largest is that of Francium (Fr). Coincidentally, these are also the most and least reactive elements.
What elements have a smaller atomic radius than strontium?
Ca, Mg, Be, Fr, Cs, Rb, K, Na, Li, H
Why does Fr have the largest atomic radius?
Many energy levels of electrons and low effective nuclear charge/low Coulombic force.
What has the greatest radius Cs Fr K Li?
Francium (Fr) down a group, the radius increases.
Is He the largest atomic size out of Li or Fr?
Fr (Francium) has the largest atomic size compared to Li (Lithium) because Francium is located at the bottom of group 1 on the periodic table, which means it has more energy levels and electron shells compared to Lithium, hence larger atomic size.
Which element of the group 1A has the largest atom?
Francium (Fr) has the largest atom among the group 1A elements. It has the highest atomic number and electron shells, resulting in a larger atomic size compared to other group 1A elements such as lithium, sodium, and potassium.
In the periodic table which one is the smallest?
radius: He ionic radius : Mn7+ electronegativity : Fr electron affinity : Fr ionization energy: H
