Ionic size refers to the size of an ion, which can be larger or smaller than the size of the corresponding neutral atom due to the gain or loss of electrons. Atomic size, on the other hand, refers to the size of an atom, typically measured as the distance between the nucleus and the outermost electron cloud. Atomic size generally increases down a group and decreases across a period on the Periodic Table.
What else can I help you with?
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 is the difference between atomic radii and ionic radii?
Atomic radii refer to the size of an atom, measured as the distance from the center of the nucleus to the outer electron shell. Ionic radii, on the other hand, refer to the size of an ion, which can be larger (anions) or smaller (cations) than the corresponding atom due to the gain or loss of electrons.
What element is the biggest ionic size?
The element with the biggest ionic size is francium due to its large atomic radius and low nuclear charge, leading to a highly polarizable electron cloud and therefore a larger ionic size.
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 happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius

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.
Why do both and atomic size and ionic size increase as you move down a group?
Both trends hold for both positive and negative ions.
Why oxygen size is bigger then zn size in Zinc oxide structure?
The larger size of oxygen compared to zinc in zinc oxide is due to the atomic radius difference between the two elements. Oxygen has a larger atomic radius than zinc, resulting in larger O atoms in the zinc oxide structure. Additionally, the bonding arrangement in the crystal structure of zinc oxide may also contribute to the perception of oxygen atoms appearing larger.
What happens to the atomic radius when an electron is lost?
the positive ionic radius is smaller than the neutral atomic radius
What is the difference between atomic size and atomic number?
The atomic number of an element determines the number of protons that are present in that element. The atomic size refers to the distance that the outermost valence electrons are from the nucleus.
Are covalent and ionic bonds the same size?
No, covalent bonds are typically shorter in length compared to ionic bonds. Ionic bonds are formed between ions that have opposite charges and are held together by electrostatic attraction, while covalent bonds involve the sharing of electrons between atoms. The difference in bond length is due to the differing nature of these interactions.
What are the factors affecting the formation of ionic compounds?
Factors affecting the formation of ionic compounds include the electronegativity difference between atoms, the size of the ions, and the lattice energy. Higher electronegativity differences between atoms lead to stronger ionic bonds. The size of the ions also affects the stability of the ionic compound, with smaller ions generally forming stronger bonds. Additionally, the lattice energy, which is the energy required to separate ions in a crystal lattice, influences the stability of the ionic compound.
What is the difference between a minivan and a van?
The difference is the size.
