Quick Answer: Does Na Or Al Have A Smaller Atomic Radius?

Which has largest radius?

(A) Comparison of Atomic and Ionic Radius of Group 1 (IA, alkali metals) ElementsElementSymbol of AtomTrendsodiumNa↓potassiumK↓rubidiumRb↓cesiumCs↓ largest1 more row.

Which has a larger radius Na+ or Na?

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 is bigger’n 3 or NE?

Which has a greater radii and why? Dear student,both have same electrons (iso electronic). Size of the species decreases with increasing protons. N has minimum 7 protons and Ne 10 protons.So nitrogen ion has greater size than neon.

Why is the atomic radius of Al smaller than na?

Due to the addition of electrons in the same shell in Aluminum, the nuclear charge on Aluminium is more than that of Na and thus the atom tends to shrink a little in size. Hence, Al has a smaller atomic size than Na.

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.

How do you calculate atomic radius?

SummaryAtomic 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 one has largest size Na+ f/f n?

Na,Na+,N,F​ – Brainly.in….Answer:F is largest in size because anions are larger than its parent atom.But since in it its valence shell has not filled, therefore it is less stable.Hence , Na is largest stable atom in these.Sep 5, 2020

Which is bigger Na or RB?

Generally, the atomic radius increases down the group. Both Rb and Na are in the same group, group 1. Rb is below Na and thus we expect Rb to have a…

Why is the ionic radius of K+ smaller than CL?

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.

Does ne or Na+ have a smaller radius?

Na+ has smaller size than Ne.

Which metal has the smallest atomic radius?

HeliumHelium 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. Atomic radius decreases as you move across a period from left to right and decreases as you move up a group from bottom to top.

Which atom is biggest in size?

franciumAs 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.

Is mg bigger than na?

(i) The sodium ion (Na+) is larger than the magnesium ion (Mg2+) due to two effects.

Does aluminum have a larger atomic radius than sodium?

Protons pull on electrons and make atoms smaller. … In this scenario, Aluminum is more to the right than Sodium, which means that it has more protons. Because of this, the protons in Aluminum pull more strongly on electrons than sodium, thus making aluminum smaller.

Which has a larger atomic radius Na or Cl?

An Na+ ion is smaller than an Na atom while a Cl-ion is bigger than a Cl atom. … In general, atomic radius is the distance between the centre of the nucleus and the outermost shell of electrons. In Na atom, the outermost shell is the ‘M’ (3rd shell)shell which has one electron. Generally, an atom is neutral.

Does NA have a bigger atomic radius than Al?

The answer is, there is an electrostatic attraction between the positively charged nucleus and the negatively charged electronic cloud, which gives the stability to the atomic system. For sure, Na+ has larger radius than Mg++. Radius is defined as the distance from the nucleus to the boundary of the surrounding cloud.

Does sodium or aluminum have a smaller atomic radius?

Of protons in aluminium(13) is more than sodium(11). That means the nuclear charge of aluminium is more and the electrons are pulled more ‘tightly’ as compared to sodium. Sodium on the other side has less nuclear charge as compared to aluminium and so the electrons are held comparatively loosely.
