Why are the ionic radii of nonmetallic elements larger than the atomic radii of those elements?
When nonmetallic elements gain electrons to form ions, the additional electrons are added to higher energy levels (shells) farther from the nucleus. This increase in the size of the electron cloud leads to an increase in the ionic radii compared to the atomic radii of those elements.
What else can I help you with?
Is the composition of an ionic compound formed by two or more nonmetallic elements?
No, ionic compounds are formed by the transfer of electrons between a metal and a nonmetal. Nonmetallic elements typically form covalent compounds where they share electrons rather than transfer them.
Why are the ionic radii of the negative ions larger than their corresponding atomic radii?
The negative ions have gained electrons, which increases the electron-electron repulsion and causes the electron cloud to expand slightly. This leads to a larger ionic radius compared to the atomic radius of the same element.
How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
Why do both atomic size and ionic size increase as you move down a group?
Both atomic size and ionic size increase as you move down a group because the number of electron shells or energy levels increases, leading to a larger distance between the nucleus and the outermost electrons. This results in a larger atomic and ionic size.
What elements have an ionic radius equal to the atomic radius?
a) Sc,Ti,V,Crb) Na,K,Rb,Csc) B,Si,As,Ted) F,Cl,Br,Ie) Na,Mg,Al,SiThe correct answer of these options is a) Sc,Ti,V,Cr because they are the closest elements to each other in the periodic table.
What kind of elements compose an ionic bond?
metallic and nonmetallic elements
Is the composition of an ionic compound formed by two or more nonmetallic elements?
No, ionic compounds are formed by the transfer of electrons between a metal and a nonmetal. Nonmetallic elements typically form covalent compounds where they share electrons rather than transfer them.
Are ionic compounds make of nonmetallic elements?
Generally ioic compounds contain metals and non metals. However the compound NH4Cl is ionic, and contains NH4+ and Cl- ,and all of the elements are non-metals.
Why are the ionic radii of the negative ions larger than their corresponding atomic radii?
The negative ions have gained electrons, which increases the electron-electron repulsion and causes the electron cloud to expand slightly. This leads to a larger ionic radius compared to the atomic radius of the same element.
What is the relationship between the atomic numbers and ionic radii of the elements in the group 3A?
I think that the ionic radii decrease
How does the ionic radius of a nonmetal compare with its atomic radius?
in the case of non-metals, the anions are formed by the addition of electrons. So the ionic radius is larger than that of the atomic radius
Why are the ionic radii of metallic elements smaller than the atomic radii of the same elements?
The ionic radii of metallic elements is smaller than its atomic radii, because the ion has less electrons. This gives it a smaller electron cloud and makes the atom smaller.
Why do both atomic size and ionic size increase as you move down a group?
Both atomic size and ionic size increase as you move down a group because the number of electron shells or energy levels increases, leading to a larger distance between the nucleus and the outermost electrons. This results in a larger atomic and ionic size.

When electrons are transfered between the atoms of metallic and nonmetallic elements what kind of bonds are formed?
When a metallic atom and a nonmetallic atom have an electron transfer to form an ion, this is known as an ionic compound. For example, salt (NaCl) an electron transfer occurs. The Na, which has 1 electron on its valence shell ( outer shell) and the Cl, which has 7 electrons on its valence shell. The Na transfers its one electron to the Cl. This therefore results in the Cl having a full valence shell; at this point Cl is negative and Na is positive. We can then conclude the NaCl is an ionic compound.
Is hexane ionic or molecular?
Hexane is a molecular compound. It consists of nonmetallic elements (carbon and hydrogen) bonded together through covalent bonds. It does not dissociate into ions in solution.
Is Cornstarch a ionic compound or molecular compound?
Cornstarch is a molecular compound because it is composed of nonmetallic elements (carbon, hydrogen, and oxygen) bonded together through covalent bonds. Ionic compounds are formed between metals and nonmetals.
