How does the size of the atomic radius in a nonmetal compare to size of its ionic radius?
I'm not positive but.... the ionic radius of a metallic atom is slammer than its atomic radius because metallic atoms want to loose electrons. The loss of electrons increases the pull of the nucleus, drawing the electrons closer and thereby making the ionic radius smaller than the atomic radius.
What else can I help you with?
Elements of which form ionic bonds between them when combined together?
Elements that form ionic bonds have a large difference in electronegativity. Typically, metals and nonmetals will form ionic bonds when combined together. In these bonds, the metal atom loses electrons to form a cation, while the nonmetal atom gains electrons to form an anion.
Water dissolves ionic compounds because water molecules?
So basically an atom of water or (H2O) is made up of two hydrogen atoms and one oxygen atom that are covalently bonded together to make a compound. A covalent bond is when two nonmetal elements, most commonly, two gases come together to make a compound. So water is a covalent bond because it is hydrogen bonded with oxygen which are both nonmetal elements being bonded together to form a covalent bond. There is a difference between ionic bonds and covalent bonds. The difference between an ionic bond and a covalent bond is that in a covalent bond the two or more elements that are being bonded together share electrons rather than take them like in an ionic compound. So with the fact that covalently bonded compounds share electrons in mind, electrons are not evenly distributed or shared throughout a water molecule because oxygen atoms strongly attract electrons. Because the oxygen atoms do this they pull electrons away from the hydrogen atoms giving them a partial positive charge. Now that the oxygen atom has the electrons closer to it than the other two hydrogen atoms it gives the oxygen atom a partially negative charge. This act of atoms not evenly sharing electrons is called a polar compound. What is special about compounds that are polar is that is attracts both positive and negative ions of an ionic commpund. Thats why water can dissolve ionic compounds because its polar structure.
Which compounds would you expect to be ionic H2O2 SF6 CaO H2O or NH3?
CaO is the only ionic
In naming a binary ionic compound the name of the appears first followed by the name of the?
In naming a binary ionic compound, the name of the cation (metal) appears first, followed by the name of the anion (non-metal). The cation keeps its elemental name, while the anion's name is modified to end in "-ide".
Which interactions and processes contribute to the dissolution of ionic compounds in water?
The process of providing energy to break ionic bonds and allow soluble ionic compounds to dissolve in water?
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
Does a metal have a greater atomic radius or ionic radius?
A metal typically has a greater atomic radius than its ionic radius. When a metal loses electrons to become a cation, the outer electrons are removed, leading to a decrease in the ionic radius compared to the neutral atom's atomic radius.
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
How does ionic radius differ from atomic radius?
Ionic radius is the size of an ion after it has gained or lost electrons, leading to a change in the electron configuration and thus its size. Atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outermost electron shell. Ionic radius is affected by the change in electron configuration, while atomic radius is more related to the position of the outer electrons in the neutral atom.
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 is hydrogens atomic radius?
* Atomic Radius: 0.79Å * Atomic Volume: 14.4cm3/mol * Covalent Radius: 0.32Å * Ionic Radius: 0.012Å * Atomic Radius: 0.79Å * Atomic Volume: 14.4cm3/mol * Covalent Radius: 0.32Å * Ionic Radius: 0.012Å
What is another word for atomic radius?
The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
Is metallic radius only for metals?
Yes. There are other measures for ions (ionic radius) and free atoms(atomic radius) and covalent radius. Metallic, ionic and covalent are based on measurements of distances in crystals or covelnt bond lengths, atomic radius is based more on calcuation than observation.
What is the relationship of ionic radius and atomic number?
As you move across a period from left to right, the atomic number increases and the ionic radius decreases. This is because the increase in positive charge in the nucleus attracts the electrons more strongly, pulling them closer to the nucleus, leading to a decrease in ionic radius.
Is the atomic radius generally smaller than the ionic radius of a non metal?
yeshttp://answers.yahoo.com/question/index?qid=20071116151305AAT0Lz3
When an atom changes into an ion besides the number of electrons what changes?
The electrical charge; also the ionic radius is different from the atomic radius.
