Which is the largest of the following species Ca2+ Cl or Ar?

Which is the largest of the following species Ca2+ Cl or Ar?

The correct option is : a Ca2+ < K+ < Ar < Cl- < S2- Explanation:Among isoelectronic ions ionic radii of anions is more than that of cations. Further size of the anion increases with increase in negative charge and size of the cation decreases with increase in positive charge.

Which is the correct order of arranging SI S mg K Cl according to increasing atomic size?

The order is: Na>Mg>Si>S>Cl.

Which is the correct electronegativity 1 point AFNO Cl BFNO Cl CFNO Cl DFON Cl?

F > O > N ≈ Cl.

Which of the following is the correct order of increasing atomic CLDI I Br Cl I Br Cl I FC BR If Cl DFI Cl Br?

Atomic size decreases from left to right in a period and increases from top to bottom in a group. Thus, the order is F.

How do you arrange ion sizes?

In such a series, size decreases as the nuclear charge (atomic number) of the ion increases. The atomic numbers of the ions are S (16), Cl (17), K (19), and Ca (20). Thus, the ions decrease in size in the order: S2- > Cl– > K+ > Ca2+.

Which is bigger Cl or S2?

S2- has one less proton than Cl-, thus there is less attraction between the protons and electrons and thus ionic radii is bigger.

How do you arrange the elements in increasing order?

Arranging the atoms We know that atomic size increases from right to left and from top to bottom in the Periodic Table. The smallest atoms are at the top right and the largest atoms are at the lower left of the Periodic Table.

How do you arrange elements in order of increasing metallic character?

Arrange the following elements in the increasing order of their metallic character: Si, Be, Mg, Na, P. Metallic character increases down a group and decreases along a period as we move from left to right. Hence the order of increasing metallic character is P < Si < Be < Mg < Na.

What is correct order of electronegativity?

The order of electronegativity is F>O>Cl>Br>S>I>C>P>H.

How do you arrange electronegativity?

Electronegativity increases from bottom to top in groups, and increases from left to right across periods. Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.

Which one of the following are correctly arranged on the basis of the increasing order of their atomic radii?

The atomic size or radius increases down a group. Therefore, the correct increasing order of atomic radii is : Cl.

What is the order of increasing atomic radius?

Atomic 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.
