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 of the following has largest radius 1s2?
Answer and Explanation:
While all of these ions and atoms have the 1s22s22p63s23p6 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 electron configuration due to the gain or loss of electrons by ions, (3) the sulfide ion S2− has the largest radius.
Which of the following has the largest radius?
Thus O2− has a minimum z-effective thus largest radius.
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 of the following ion has largest radius?
Ernest Z. K+ has the largest radius.
Which of the following has the largest radius answers com?
Jupiter is the largest planet and therefore has the largest radius.
Which of the following has the smallest radius?
Helium has the smallest atomic radius.
Which has largest radius CO 3?
a)Cr3+b)Mn3+c)Fe3+d)Co3+Correct answer is option ‘C’.
Which of the following has the largest radius K Na+ Na K+?
K+ has a larger atomic radius than Na+. The Periodic Table is accompanied by many trends. One such trend involves the atomic radius for these elements. As you go down the periodic table, the atomic radius increases which is why K+ has a larger radius… it’s below Na+.
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 element has the largest atomic radius K or Na?
As an example, potassium (K) has a larger average atomic radius (220 pm)than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius.
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.
How do you find atomic radius?
Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.
Which of the following ions is the largest?
Answer. Na+ is the largest ion in this group because Na+ has only one electron less than the number of protons it has whereas Mg has 2 and Al has 3 less electrons than their respective proton numbers,so the shielding effect is more in Na+,thus larger size.
Which has the largest radius O or O 2?
O2− is larger than O because the increase in electron repulsions that accompany addition of an electron causes the electron cloud to expand. O2− is larger than O because O is neutral but O2− has a charge 2−. … S2− is larger than O2− because for particles with like charges, size increases going down a family.
Why is K bigger 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.
