Atomic size generally increases as you move down a group in the Periodic Table due to the addition of electron shells, which places the outermost electrons farther from the nucleus. Conversely, atomic size decreases across a period from left to right as the effective nuclear charge increases, pulling the electrons closer to the nucleus. This trend is influenced by factors such as electron shielding and the overall increase in nuclear charge.

What atom is bigger in size vanadium or platinum?
Vanadium is typically larger in size compared to platinum. This is because as you move across a period in the periodic table, the atomic radius generally decreases due to increasing nuclear charge, while moving down a group leads to an increase in atomic size. Vanadium is in a lower period (4th) than platinum (6th) in the periodic table, resulting in a larger atomic size for vanadium.
Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
In general howe dose atomic radius change across a period from letf to right?
Atomic radius generally decreases across a period from left to right. This is due to the increasing nuclear charge pulling the electrons closer to the nucleus, making the atomic size smaller.
How does atomic size generally go on the periodic table?
Atomic size generally decreases across a period from left to right due to increasing effective nuclear charge, which attracts the electrons more strongly, pulling them closer to the nucleus. Atomic size generally increases down a group due to the addition of new energy levels further away from the nucleus.
What elements has the smallest atomic size K Ca Na Ar or Kr?
The element with the smallest atomic size is Argon (Ar) as it has the highest atomic number among the options given. Atomic size generally decreases from left to right across a period in the periodic table.
Is the atomic size of francium greater than that of cesium?
Yes, the atomic size of francium is greater than that of cesium. Francium is located below cesium in the same group on the periodic table, so as you move down the group, atomic size generally increases.
Who has a bigger atomic size potassium or copper?
Potassium has a bigger atomic size than copper. This is because as you move down a group in the periodic table, the atomic size generally increases due to the addition of more electron shells. Potassium, being below copper in the periodic table, has a larger atomic size.
What is the difference between ionic size and atomic size?
Ionic size refers to the size of an ion, which can be larger or smaller than the size of the corresponding neutral atom due to the gain or loss of electrons. Atomic size, on the other hand, refers to the size of an atom, typically measured as the distance between the nucleus and the outermost electron cloud. Atomic size generally increases down a group and decreases across a period on the periodic table.
What atom is bigger in size vanadium or platinum?
Vanadium is typically larger in size compared to platinum. This is because as you move across a period in the periodic table, the atomic radius generally decreases due to increasing nuclear charge, while moving down a group leads to an increase in atomic size. Vanadium is in a lower period (4th) than platinum (6th) in the periodic table, resulting in a larger atomic size for vanadium.
Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
How do the atoms of elements 19 and 35 compare in size?
The atom of element 19 (potassium) is larger in size than the atom of element 35 (bromine) because atomic size generally increases as you move down a group in the periodic table. Potassium is in a lower period and has more electron shells than bromine, which contributes to its larger atomic size.
What is the periodic trend for atomic size from top to bottom in a group?
Atomic size generally increases from top to bottom within a group on the periodic table. This is because each successive element has an additional energy level of electrons, leading to increased electron-electron repulsion and an overall increase in atomic size.
What pattern in atomic size occurs in the periodic table?
In the periodic table, the atomic size increases with every period due to addition of an extra shell. The atomic size decreases with every group since no. of electrons and protons are increased with every group across a period leading to extra electrostatic force of attraction between electrons and the nucleus and thus shrinking the size of the atom.
What is the Atomic size of oxygen?
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.
