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.
Which of the following elements has the largest atomic radius quizlet?
Therefore, rubidium has the largest atomic radius whereas helium has the smallest.
Which of the following element have some atomic radii?
Hence, the values of atomic radii given here in picometers can be converted to atomic units by dividing by 53, to the level of accuracy of the data given in this table.
…

Which element has the largest atomic radius Asnpsb?
- Answer : ‘Sb’ is the element which has the greatest atomic radius.
- Explanation :
- The general trend of the atomic radium of the element is that,
- Hence, ‘Sb’ is the element which has the greatest atomic radius.

Which of the following halogens has the largest atomic radius?
(B) Trends in the Atomic Radius of Group 17 (VIIA, Halogens) Elements
| Element | Atomic Number (Z) | Trend |
|---|---|---|
| fluorine | 9 | (smallest) ↓ |
| chlorine | 17 | ↓ |
| bromine | 35 | ↓ |
| iodine | 53 | ↓ (largest) |
Which element has the largest atomic radius Na Mg K Ca?
Answer: Potassium (K) with an atomic number of 19 has the largest atomic radius. This is because sodium and potassium are elements of group 1. On moving from top to bottom in a group, the atomic radius increases.
Which element has the largest atom?
Cesium (Cs), tucked in the lower left hand corner of the table, has the largest known atoms.
Which element has the largest atomic number?
Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.
Which element has the smallest 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.
Which element has the largest atomic radius N or P?
Thus as group 14 elements are arranged in group as N, P , As and Sb, Sb has largest atomic radius.
Which element has a larger atomic radius than phosphorus?
Atomic Radius of the elements
| Helium | 31 pm | 161 pm |
|---|---|---|
| Phosphorus | 98 pm | 183 pm |
| Selenium | 103 pm | 184 pm |
| Xenon | 108 pm | 185 pm |
| Silicon | 111 pm | 188 pm |
Which noble gas has the largest atomic radius?
As you go down a group, the atomic radius increases because you are adding energy levels that are farther away from the nucleus. Smallest to Largest: Helium.
…
Largest to Smallest:
- Helium (highest ionization level in the periodic table)
- Neon.
- Argon.
- Krypton.
- Xenon.
- Radon.
Do noble gases have the largest atomic radius?
Why do noble gases have larger atomic radii? Its because they have fully filled octet so, electron-electron repulsion greater in them. … This is the reason why vanderwaals radius is always greater than covalent radius. Therefore noble gases have largest radii in their respective period.
Why does lithium have the largest atomic radius?
The effective nuclear charge is simply a measure of the net positive charge that affects the outermost electrons in an atom. In lithium’s case, the outermost electron is being screened from the nucleus by two core electrons. … That is why lithium has a larger atomic radius than beryllium.
