How is the radius of an atom related to the atoms attraction for outer level electrons?
As the radius of an atom increases, the attraction between the positively charged nucleus and the negatively charged outer level electrons decreases. This is because the outer level electrons are farther away from the "home base." So, as atomic size (radius) increases, the nucleus has less and less a hold on those outermost electrons. For this reason, cesium (Cs, atomic #55) has very large atomic size and very low electronegativity. Fluorine (F, atomic #9) has very small atomic size but large electronegativity.
What element have the smallest atomic radius?
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.

Which atom has the smallest atomic radii?
Helium has the smallest atomic radius among all the elements on the periodic table. This is because helium has a small number of electron shells and a strong nuclear attraction, which results in a compact atomic structure.
Elements, like calcium, located toward the top of a group have a high attraction for their valence electrons because they have a _?
small atomic radius.
What are 3 atoms that have the highest electronegativities?

B. are located on the right on the Periodic TableC. have a small atomic radius
Is polonium big or small?
If you think to the atomic radius the empirical atomic radius of polonium is 168 pm.
Does francium have a small radius?
The covalent atomic radius of francium is 260 pm and this value is not small.

Why does lithium have a low electron negativity when fluorine has a high electron negativity?
Lithium has a low electronegativity because it has a relatively large atomic radius and easily loses its outer electron. Fluorine, on the other hand, has a high electronegativity due to its small atomic size and strong attraction for gaining electrons to achieve a full outer electron shell.
Why is the electronegativity of galilium higher than that of aluminum?
Gallium, and geranium for that matter, have higher electronegativity's than aluminum (and silicon) because of their d-block contraction. The 3d-electrons do not shield the increased nuclear charge on these elements in the fourth period after the first row of transition metals. This gives them an unusually small atomic radius and a higher electronegativity.

Elements like francium located at the bottom of a group have a lower attraction for their valence electrons because they have a?
higher atomic number and larger atomic size, causing their valence electrons to be farther away from the nucleus, resulting in a weaker attraction. Additionally, the shielding effect of inner electron shells reduces the effective nuclear charge felt by the valence electrons, further decreasing the attraction.
What is the atomic radius of helium and how does it compare to other elements in the periodic table?
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the periodic table due to its small size and high nuclear charge.
What does pm stand for in an atomic radius for?
pm stands for picometers in an atomic radius measurement. It is a unit of length equal to one trillionth of a meter, commonly used in atomic scales due to their extremely small size.
Which atom has the smallest atomic radii?
Helium has the smallest atomic radius among all the elements on the periodic table. This is because helium has a small number of electron shells and a strong nuclear attraction, which results in a compact atomic structure.
What element have the smallest atomic raduis in Group 7A?
Fluorine, as a halogen in Group 7A of the periodic table, has the smallest atomic radius due to its high effective nuclear charge and strong attraction for electrons. This makes the fluorine atom very compact with a small atomic radius compared to other elements in the same group.
