Which ion is smaller Cl or K+?
In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons.
This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation.
Therefore, the chloride anion will have the larger atomic radius..
What is atomic radius of neon?
38 pmNeon/Atomic radius
Why is neon smaller than carbon?
Carbon (atomic number = 6) and neon (atomic number = 10) both have their outermost electrons in 2p orbitals. Explain why neon is smaller than carbon even though it has more electrons. neon has additional protons as part of its nucleus to attract valence electrons 7.
Which is bigger H or F?
no actually flourine anion is larger in size than H anion. … Both of them H,F ions are smaller in size.
Which atom is the largest?
franciumAtomic 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 is smaller in size Li or F?
Potassium and rubidium are both larger than lithium because atomic size increases going down in a group. Fluorine is in the same period as lithium but to the right of lithium so it’s smaller which means Li is larger in size than F.
Which has a larger atomic radius O or o2?
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−.
What is the smallest atomic radius?
HeliumWhich element 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.
Why is fluorine smaller than lithium even though it has much more mass?
Because of the increased nuclear charge in fluorine, which has nine protons, the electrons in the L shell are bound more closely than in lithium, which has only three. A lithium atom is therefore larger than a fluorine atom, even though it contains less mass.
Which is bigger Li or be?
Explanation: Lithium, Li , and beryllium, Be , are both located in period 2 of the periodic table, in group 1 and group 2, respectively. For both these elements, the outermost electrons are located on the second energy level in the 2s-subshell. … That is why lithium has a larger atomic radius than beryllium.
Is Neon bigger than fluorine?
Neon has weak van der waals forces. So neon is large in size than fluorine.

What is the trend in atomic radius from left to right across a period?
WHY? – The number of energy levels increases as you move down a group as the number of electrons increases. Each subsequent energy level is further from the nucleus than the last. Therefore, the atomic radius increases as the group and energy levels increase. 2) As you move across a period, atomic radius decreases.
Is Li+ larger than li?
Size of Li+ is 0.74A° whereas that of Mg2+ is 0.72A°. That’s why lithium and magnesium have diagonal relationship in their chemical properties. Li+ is greater than Mg2+ because of higher charge on nucleus of Magnesium 2+.
