Which has largest radius?
Atomic radii are measured in picometers (one picometer is equal to one trillionth of a meter). Hydrogen (H) has the smallest average atomic radius at about 25 pm, while caesium (Cs) has the largest average radius at about 260 pm.
Which of these has the largest atomic radius?
The third period will have larger atomic radius than the second period since the third period lies below the second period. Moreover, Na lies to the left of the periodic table and Cl lies to the right of the periodic table. Hence Na has the largest atomic radius of the above-mentioned elements.
Which has a larger radius Na or Na 1?
So p/e ratio is 1 and Na+ ion nucleus has eleven positive (p) charge and ten negative charge (e). … As is known from the chemistry course, when the element loses electron (turn into cation, with positive charge), the atom radius is getting low, so obviously Na+ is smaller than Na.
Which has the largest radius Co3+ Mn3+ fe3+ Cr3+?
Fe 3+ has highest radii because by going left to right in the periodic table , the size get decreased so .. Fe 3+ >Co3+ >Cr3+ >Mn3+ .
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.
Which has a larger atomic radius Cl or Br?
Likewise, bromine will have a larger atomic radius when compared with chlorine. … 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.
Which has the largest atomic radius mg Si S or Na?
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.
Is BR or BR 1 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.
Which is bigger Na or RB?
Answer and Explanation:
Generally, the atomic radius increases down the group. Both Rb and Na are in the same group, group 1. … Sodium (Na) has a radius 186 pm whereas Rubidium (Rb) 248pm and thus rubidium is bigger than sodium.
Which is bigger Na or Na+?
The total number of electrons is 10 in case of Na+ and 11 in case of Na, while the number of proton is same i.e. 11 in both case.
Which of the following has the largest radius O2 F Na+ mg2+?
d- F- Ionic radius increases with increase in positive charge on isoelectronic species. Here, Mg+2 will have largest ionic radius.
Which of the following has the largest radius FCNO?
As we can see, only Potassium has four electron shells, therefore Potassium has the largest atomic size. Showing once again how Potassium has the largest atomic radius, and therefore the largest atomic size.
Which ion has largest radius?
1 Answer. Ernest Z. K+ has the largest radius.
