I find this one very peculiar myself. I was searching for the answer too, because it doesn't make sense. What I found was that for both the elements their periodnumber and their atomic number where the same, But Cromium has one more valence electron so also slightly more screening effect. So why is it that it's radius is smaller as the one of Vanadium? Well my chemistry book says this phenomenon can be seen with elements in the D-or F blocks. Why? I don't know. It only states that the radiae COULD increase from the left to the right. So if I where you (and I am becouse tomorrow I will have a test about this) I'd just learn it by hard and hope to give the right answer. Many luck with it!
What else can I help you with?
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 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.
What is the element in period 4 with the smallest atomic radius?
The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.
Electronegativity increases when atoms .?
B. are located on the right on the Periodic TableC. have a small atomic radius
Why does the atomic radius decrease with an increase in atomic numbers within a period?
As the atomic number increases, the number of protons in the nucleus increases or the effective nuclear charge of the nucleus increases. As a result the force exerted by the nucleus on the valence electrons is more or the size of the atom is small.
Where is Cr on the periodic table?
well you see tht thing is ur small dick now help me wiki
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.
Does a small atomic radius correspond with a high or low electronegativity?
A small atomic radius corresponds more closely to a low electronegativity.
How many neutrons are in a chromium element?
A typical chromium atoms has 28 neutrons. Because electrons are so small, virtually all of the atomic mass comes from the protons and neutrons. By subtracting the number of protons (equal to the atomic number) from the total atomic mass, the number of neutrons is obtained. For chromium atomic mass- 52 atomic number (number of protons) - 24 number of neutrons 52-24=28
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.

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.
Why does iron tend to form a bond with vanadium?
I would not say that iron does "tend to form a bond with vanadium". Certainly vanadium is present in small amounts in some steels for example . An alloy ferro vanadium is produced industrially and used in steel manufacture.
