What element or ion has the electron configuration 1s 22s 22p 6?

element Silicon

Which orbitals have the most energy?

The energy of an electron versus its orbital Within a given principal energy level, electrons in p orbitals are always more energetic than those in s orbitals, those in d orbitals are always more energetic than those in p orbitals, and electrons in f orbitals are always more energetic than those in d ortitals.

What element in the second period has the largest atomic radius?

francium

Which period has the smallest atomic radius?

Helium

Which ion has largest radius?

K +, Cl −, and S 2− form an isoelectronic series with the [Ar] closed-shell electron configuration; that is, all three ions contain 18 electrons but have different nuclear charges. Because K + has the greatest nuclear charge (Z = 19), its radius is smallest, and S 2− with Z = 16 has the largest radius.

Is O2 bigger than F?

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.

Which ion has the largest radius Se2 F O2 Rb+?

Answer. Answer: The answer is “Rubidium Rb+”.

What is the atomic radius of Rb+?

The atomic radius for Rb is 265pm and it is 88pm for Kr.

Which ion has the smallest radius?

Oxygen

Which ion has the largest radius Cl F K+ cu2+?

So it has 18 electrons, so it could be either chloride ion or potassium ion as the answer here. Remember when the number of electrons were tied? We’re gonna say the MAWR negative charge is the larger ion.

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.

Which is larger K+ or Ca2+?

(d) K+ is larger than Ca2+ Isoelectronic; Ca2+ has more protons to pull e- inward.

Which is larger K+ or Ar?

Explanation: And for NEUTRAL atoms, reasonably, atomic size decreases across a Period, from left to right as we face the Table, and INCREASES down a Group. With respect to the parent atoms, potassium would be larger than argon, the which would be smaller than chlorine.

Is chlorine bigger than oxygen?

We confirm this by looking at the atomic radius of oxygen and chlorine, seeing that oxygen is a smaller atom than chlorine, and thus that the force felt by the outermost electrons to the nucleus pull oxygen’s electrons more chlosely than chlorine’s.

Which is smaller in size Li or F?

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.

What is the ionic radius of K+?

280 pm

Which is bigger Na or Na+?

The total number of electrons is 10 in case of Na+ and 11 in case of Na, while the number of proton is same i.e. 11 in both case.

What is Br radius?

185 pm

How do you find ionic radius?

Ionic radius is determined by measuring the atom in a crystal lattice. Removal of electrons results in an ion that is smaller than the parent element. Addition of electrons results in an ion that is larger than the parent atom.
