Is arsenic similar to germanium?
Germanium is the third element of the fourteenth column of the periodic table. It is similar in properties to the other metalloids near it in the periodic table which are silicon and arsenic.
Which atom is biggest in size?
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 elements have the largest atomic radius?
Explanation: Francium has the largest, Helium has the lowest. Atomic radius increases as you go to the left and downward due to the attraction of electrons and the nucleus in an atom.
Does carbon or germanium have a larger atomic radius?
Carbon also has a significantly smaller radius, higher electronegativity, and a higher ionization energy….Physical Properties.
| element | germanium |
|---|---|
| atomic radius | 122 pm |
| electronegativity | 2.02 |
| melting point | 1211 K |
| ionization energy | 762 kJ/mol |
What is the atomic radius of arsenic?
185 pm
Which particle has a larger radius?
is positively charged cation formed by losing 1 electron, so Na has larger radius. Na has the larger radius because cations are usually smaller than the neutral atom they originated from.
Which ion has the largest radius?
Consequently, the ion with the greatest nuclear charge (Al3+) is the smallest, and the ion with the smallest nuclear charge (N3−) is the largest….Ionic Radii and Isoelectronic Series.
| Ion | Radius (pm) | Atomic Number |
|---|---|---|
| N3− | 146 | 7 |
| O2− | 140 | 8 |
| F− | 133 | 9 |
| Na+ | 98 | 11 |
Which particle has the larger radius Al or Al3+?
It’s radius is larger than both S and Al. And as you noticed already, Al3+, having lost three electrons would have the smallest atomic radius.
Does Al or B have a larger radius?

Which is larger F or Li+?
In your case, lithium has an atomic number equal to 3 and fluorine an atomic number equal to 9 . So fluorine has more protons in its nucleus. Keep this in mind. As a result, the atomic size of fluorine will be smaller than that of lithium, or, in other words, lithium will have larger atomic radius than fluorine.
Is BR bigger than Kr?
Br- has to be larger than Kr because it has one less proton, hence electron repulsion is more pronounced.
Is K or K+ bigger?
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 MG bigger than mg2+?
So Mg atom will be larger as it has more electrons than Mg 2+ and thus will have larger atomic radii.
Which atom is larger S or O?
S2- is larger than O- because S2- has more protons and thus a stronger pull on its electrons than O- does, so it has a smaller atomic radius.
Which is bigger S or S 2?
(ii) Explain why the radius of the S2- ion is larger than the radius of the S atom. The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom.
Why is atomic radius of K greater 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.
Is F bigger than F?
More the atomic number size becomes larger. So F- is larger in size.
Which is larger F or F minus?
F has a larger radius than F− because an additional electron causes greater repulsion in F.
Why does f have a bigger radius than F?
We know that F and F- are both smaller than the rest because they have less shells. Now between F and F-: F- has one more electron, which causes the radius to be bigger.
