Therefore the largest atoms are on the left and the smallest on the right. So sodium (Na) has the largest atomic radius, as the valence electrons are the least attracted to the nucleus.
Does Na or Mg have a larger atomic radius?
Explanation: Given that atomic size decreases across a Period, the sodium atom is larger than that of magnesium. Both third row metals are larger than second row beryllium, inasmuch as the third Period metals build on the atomic radius (the electron shell) already possessed by the second Period.
Which has the largest atomic radius magnesium mg Silicon Si sulfur S or sodium NA )?
sodium (Na) has the largest radius. sulfur (S) has the smallest radius.
Which has the largest atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Is Br or F bigger?
Explanation: Fluorine is in group 7A and period 2 making it the smallest of the 5 atoms here. Br is also in group 7A but is in period 4 making it larger than F, Ge is in group 4A and also in period 4 but is to the left of Br making it larger than Br.
Is Br or Br bigger?
Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.
Does silicon have the largest atomic radius?
The largest and smallest atoms.

atoms.
| Element | silicon |
|---|---|
| Symbol | Si |
| Atomic number | 14 |
| Atomic radius in nanometers | 0.117 |
What has the smallest atomic radius?
Explanation: Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus.
Is K or K+ larger?
When at neutral, the potassium ion in the form of K has an electronic configuration of: … The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence, K is larger than K+.
Why is the atomic radius of k larger than Br?
Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.
What element has the second largest atomic radius?
(A) Trends in the Atomic Radius of Elements in Period 2
| Element | Li | Be |
|---|---|---|
| Energy Level being filled (Valence Shell) | second (L) | second (L) |
| Nuclear Charge (charge on all protons) | 3+ | 4+ |
| Atomic Radius (pm) | 134 | 90 |
| General Trend | (largest) | → |
What is the atomic radius of O?
152 pm
Which one has the largest size BR I?
Br is placed above I in periodic table. Thus Br is smaller than I+,I,I−. Among I+,I,I− the lowest effective nuclear charge is experienced by I−. Thus it has largest size.
Why is CL larger than Na+?
Na atoms are larger than Cl atoms because the electron cloud of Cl is pulled in more tightly by the increased number of protons in the nucleus. Na+ ions are smaller than Cl- ions because the Na+ ions have electrons in only two energy levels and Cl- ions have electrons in three levels.
Which one has the largest size BR I CL?
Why iodine has a largest size among ,Br,I,I-,Cl.
