Which atom or ion has the smallest radius?
The atomic radius of gas rises from top to bottom in a group and drops from left to right across a period.
The radius of an atom is determined by the distance between the nucleus and the outermost orbital electrons.
Which ions have the smallest radius?
Because K has the greatest nuclear charge (Z = 19), its radius is the smallest, and S 2- with Z = 16 has the largest radius.
Which of the following ion has the smallest ionic radius?
Li+, B3+ and re smaller than N3− and O2− since they have a lower nuclear charge. Due to its greater nuclear charge, B3+ is smaller because electrons are strongly attracted by it. As a result, among the choices presented, B3+ is the smallest.
Which of the following atoms has the smallest radius?
The atomic radius of helium is the smallest.
Which ion has the largest radius?
The K+ radius, which is the distance from one end of the curve to another, is the largest.
Which ion is the smallest?
The greater the nuclear charge on an ion, the more strongly attracted are its electrons and ,the smaller it gets. Al3+ is the tiniest ion among those listed.
Is K+ or Ca2+ bigger?
K+ is greater than Ca2+, owing to the fact that it has more protons to tug e- inwards.
Is K+ bigger than K?
When K loses its outermost single electron to acquire the “electronic configuration” of: The K+ ion now has its outermost electrons on the third energy level and is smaller in size than the K ion. As a result, K is greater than or equal to K+.
What is the ionic radius of K+?
Which of the following atoms has the largest radius?
The most massive of the elements listed is Cesium, whose atomic radius is greater than that of any other element.
Which of the following atoms has the largest atomic radius *?
Chlorine is the smallest atom with the greatest atomic radius. Because fluorine is in the same period as oxygen and to its right, it can be excluded. Because chlorine is the farthest down the group of the above elements listed, it has the largest atomic size.
Which element has the largest atomic number?
The heaviest element in the periodic table, oganesson contains the greatest atomic number and weight. The radioactive oganesson atom is extremely hazardous; nevertheless, only five (possibly six) atoms of the isotope oganesson-294 have been discovered since 2005.
