Atomic radius increases down a group on the Periodic Table because with each additional period an energy level is added.

How does atomic radius vary down the group iv elements?
Atomic radius in group 4:- titanium=140 pm- zirconium=155 pm- hafnium=155 pm
What has an atomic radius bigger than sulfur?
Elements with an atomic radius larger than sulfur (atomic number 16) include phosphorus (atomic number 15) and chlorine (atomic number 17), as well as all elements in the rows below sulfur in the periodic table, such as selenium (atomic number 34) and tellurium (atomic number 52). Generally, atomic radius increases down a group due to the addition of electron shells, and it can vary across periods due to effective nuclear charge.
In the ground state an atom of each of the elements in Group 2 has a different?
In the ground state, an atom of each of the elements in Group 2 (the alkaline earth metals) has a different atomic radius due to increasing nuclear charge as you move down the group. This increased nuclear charge pulls the electron cloud closer to the nucleus, resulting in a larger atomic radius. Additionally, the presence of more electron shells as you go down the group contributes to this increase in size, despite the stronger nuclear attraction. Thus, while they all have similar chemical properties, their atomic sizes vary significantly.
What is the atomic radius phosphorus?
The atomic radius of phosphorus is approximately 110 picometers (pm) or 1.1 angstroms (Å). This value can vary slightly depending on the specific allotrope of phosphorus and the method of measurement. Phosphorus, located in group 15 of the periodic table, has a relatively smaller atomic radius compared to elements in the same period, such as silicon and sulfur.
Do all atoms have same radius?
No, not all atoms have the same radius. Atomic radii vary significantly depending on the element and its position in the periodic table, influenced by factors such as the number of electron shells and the effective nuclear charge. Generally, atomic size increases down a group and decreases across a period due to changes in electron shielding and nuclear charge.
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 size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
How do the sizes of atoms vary within a group (family)and explain why?
The atomic radius increase down in a group; the cause is the lower attraction from the nucleus atoms with increased bigger atomic mass.
What has an atomic radius bigger than sulfur?
Elements with an atomic radius larger than sulfur (atomic number 16) include phosphorus (atomic number 15) and chlorine (atomic number 17), as well as all elements in the rows below sulfur in the periodic table, such as selenium (atomic number 34) and tellurium (atomic number 52). Generally, atomic radius increases down a group due to the addition of electron shells, and it can vary across periods due to effective nuclear charge.
How does the atomic radius vary in a period?
Atomic radius decreases across a period from left to right, except for the noble gases.

What is the distance from the center of the nucleus of an atom to its outermost electron?
for hydrogen it is about 37 pico-meters. larger atoms (larger than H or He) have a second, or even 3, 4, 5, 6, or 7 orbitals of electrons. Francium, #87 has an atomic radius of 270 p-m. Much bigger, but way tiny compared to you.
How does the ionization energy vary with atomic number within the group?
Ionization energy generally decreases as you move down a group in the periodic table. This is because as you move down a group, the outermost electrons are farther from the nucleus, resulting in weaker attraction and easier removal of electrons.
Is the two atoms have same atomic radius?
Not necessarily. The atomic radius of an element is determined by the size of the atom's electron cloud. While atoms of the same element would typically have the same atomic radius, atoms of different elements can vary in size due to differences in their electron configurations and the number of protons in their nuclei.
