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.
When metals become ions what happens to their atomic radius?
Metals generally become cations and thus lose electrons and their atomic radius shrinks. This is because the metals will lose a shell of electrons and the nucleus' pull on the electrons will become more concentrated, pulling them closer.
Why does the atomic radius change as electrons are added to a shell?
The atomic radius decreases as electrons are added to a shell because the increasing number of electrons increases the electrostatic force of attraction between the electrons and the nucleus, pulling the electrons closer to the nucleus and reducing the atomic radius.
When does the atomic radius of an atom increase?
the radius of an atom gets larger when moving left to right across the Periodic Table because elements gain protons and electrons- the increase in charge brings the atom radius in
Why does the atomic radius increase as you go down the familY?
Because you have more electrons in the atom
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
Why does the size of the elements increase down a group?
The atomic numbers of the elements down a group increase. this means, more electrons. More electrons mean more shells. More shells mean larger radius. Larger radius is nothing but larger size. Thus, the number of electrons or shells is the reason why the size of the atom of elements increase down the group.
Why the atomic radius increase in column of periodic table?
The atomic radius increases down a column in the periodic table because as you move from top to bottom, each element has an additional energy level or shell of electrons. This increase in electron shells results in a larger average distance between the nucleus and the outermost electrons, leading to a larger atomic radius.
Would the same behavior exist in atomic radius for the ions of atoms?
No, the behavior of atomic radius for ions of atoms would not be the same. When an atom gains or loses electrons to become an ion, its radius changes. Cations (positively charged ions) are smaller in radius compared to their parent atoms because they lose electrons, leading to increased effective nuclear charge pulling the remaining electrons closer. Anions (negatively charged ions) are larger in radius as they gain electrons, resulting in increased electron-electron repulsion and expansion of the electron cloud.
Why does an increase in atomic radius lead to a lower ionization energy?
An increase in atomic radius leads to a lower ionization energy because the outermost electrons are farther away from the nucleus, which weakens the attraction between the electrons and the nucleus. This makes it easier to remove an electron, resulting in a lower ionization energy.
How can you can increase or decrease the energy possessed by electrons?
To increase the energy possessed by electrons, you can provide them with external energy sources such as heat or light. This can excite the electrons to higher energy levels. To decrease their energy, you can remove external energy sources, causing the electrons to lose energy and move to lower energy levels.
Why are size of cations always smaller and size of anions always bigger than the corresponding atom?
anions always gain extra electrons casing the ionic radius to increase but cations remove electrons causing the ionic radius to decrease .therefore anionic radius is greater than cationic radius
