The positive ionic radius is smaller than the neutral atomic radius
What else can I help you with?
Why pottasium with atomic number 19 is more reactive than lithium with atomic number 3?
potasium has larger atomic radius so loses electrons more readily. All alkali metals are very reactive, but each one is slightly more reactive than the one directly above it in the periodic table. Tha larger the atomic radius the weaker the attractive force will be so the electrons farther from the nucleus are lost more easily during the reaction.
What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
What is the atomic structure of Ca 2 plus?
40 Ca2+ Mass number is 40 Atomic number (proton number) is 20 therefore 18 electrons as calcium has lost 2 electrons to become a Ca2+ ions :D
What happens with the electrons when an atom froms a cation and an anion?
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
What happens to an uncharged object when it comes in contact with a charged object.After the object that was charged lost electrons and the uncharged object gained electrons?
It becomes charged. (negatively)
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 is the type of atomic bond that exists when valence electrons are lost or gained?
covalent bond
How does the size of a magnesium ion with a 2 charge compare with that of a sodium ion with a single plus charge?
The Na+ will have a larger size (atomic radius) while Mg2+ will have relatively smaller size. Both elements have lost their valence (outermost) electrons and achieve a stable octet state as ions. what makes a difference is the effective nuclear charge. because Mg has a higher nuclear charge, the valence electrons are pulled more towards the nucleus thereby reducing the atomic radius.
What atom has higher atomic radius Na or Na plus?
Na atom has a higher atomic radius compared to Na+ ion. This is because Na+ ion has lost an electron, leading to a decrease in electron-electron repulsion and a smaller electron cloud, causing the ion to have a smaller atomic radius than the neutral Na atom.
When do atoms have a positive charge?
When they have lost 1 or more electrons, possibly in a atomic bonding situation, or due to collisions.

40 Ca2+ Mass number is 40 Atomic number (proton number) is 20 therefore 18 electrons as calcium has lost 2 electrons to become a Ca2+ ions :D
What happens with the electrons when an atom froms a cation and an anion?
A cation is an atom that has lost one or more electrons. An anion is an atom that has gained one or more electrons.
What is the atomic number of ion?
Ions do not have an atomic number as they are atoms or molecules that have gained or lost electrons, altering their charge. The atomic number of an element is the number of protons in the nucleus of an atom.
What happens when a neutral atom becomes positive?
the excess protons pull harder on the fewer neutrons
Why are the ionic radii of positive ions smaller than their corresponding atomic radii?
Positive ions have lost electrons, resulting in fewer electron-electron repulsions within the electron cloud, causing it to shrink. This leads to a smaller ionic radius compared to the corresponding neutral atom.
