What is the atomic radius of an atom?
Atomic radius: The radius of an atom. This distance between an atom’s nucleus and outer electron shell. Atomic radius differs with the bonding state of an atom (for example an nonbonded atom of an element versus the same element within a covalent bond).
What element has the largest atomic radius?
francium
Which has a larger atomic radius Na or MG?
Explanation: Given that atomic size decreases across a Period, the sodium atom is larger than that of magnesium. Both third row metals are larger than second row beryllium, inasmuch as the third Period metals build on the atomic radius (the electron shell) already possessed by the second Period.
Which is larger Na+ or F?
Na+ has smaller size than F- because both Na+ and F- have equal number of electrons i.e.10 . After losing an electron Na will have less electron cloud and more effective nuclear charge whereas F after gaining an electron will have less effective nuclear charge than the parent atom so the size increases .
Does O or F have a larger atomic radius?
So they should be roughly the same size. But fluorine has an extra proton in the nucleus which draws the electrons ever so slightly closer, even considering that fluorine has one more electron than oxygen. This forms a general trend that as you move from left to right, atomic radius decreases.
Which element has a larger atomic radius sodium or lithium?
Sodium is in period 3 in group 1/IA, so its valence electron is in the third energy level, therefore it has a greater atomic radius than lithium. The size of an atom is usually known as its atomic radius.
Is mg2+ bigger than Na+?
mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus. …
Is F bigger than O2?
Explanation: From top to bottom of the periodic table ions will increase in radii. However, now left to right the radius is more of a function of the number of electrons. Similarly, O2- will be larger than F- as both have 10 electrons but Z=8 for oxygen and Z=9 for fluorine.
Is potassium bigger than chlorine?
The potassium atom (K) is larger than the chlorine atom (Cl), but the potassium ion (K+) is smaller than the chlorine ion (Cl-).
