atomic radius increases as you go down the group and decreases as you go across the period therefore the smallest atomic radius for group 14 is carbon.

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.

What group of elements have members of the smallest atomic radii for a given period?
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.
What elements has the smallest atomic radius bromine sulfur chlorine or selenium?
Among bromine, sulfur, chlorine, and selenium, chlorine has the smallest atomic radius. This is because atomic radius decreases as you move from left to right across a period on the periodic table. Chlorine is located on the right side of the periodic table in the 17th group, which indicates smaller atomic radius.
What elements has the smallest atomic radius Ge Se Br As?
The element with the smallest atomic radius among Ge, Se, Br, and As is Arsenic (As). Atomic size generally decreases across a period from left to right, so the elements in this group progress in order of increasing atomic radius: Germanium (Ge) > Selenium (Se) > Bromine (Br) > Arsenic (As).
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 species has the smallest atomic radius between Kor Mg orRb or Ca?
The species with the smallest atomic radius among K, Mg, Rb, and Ca is Rb (Rubidium). This is because atomic radius tends to decrease across a period from left to right in the periodic table, and Rb is located towards the right side of this group of elements.
What group of elements have members of the smallest atomic radii for a given period?
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.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
How are period and group trends in atomic radii are related to electron configuration?
Period trends in atomic radii show a decrease across a period due to increasing nuclear charge and more protons pulling electrons closer. Group trends in atomic radii show an increase down a group due to additional energy levels being added, leading to larger atomic size. Electron configuration influences these trends by determining the number of energy levels and electron shielding in an atom, affecting the distance of the outer electrons from the nucleus.
Do transition elements follow the same trend of atomic radius as the main group elements?
NO
Which of these elements has the largest atomic radius. Aluminum potassium fluorine. Calcium?
Potassium has the largest atomic radius. It is in the 1st group of the periodic table. Fluorine has the least atomic radius.
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.
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 elements boron aluminum gallium or indium has the largest atomic radius?
Atomic radius increases down the group. So indium will have the largest atomic radius among the options given.
Why same group elements have irregular atomic radius?
because of atomim configration
How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
How does the presence of core electrons affect the atomic radius of elements?
When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)
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
