What happens to the atomic size of the atoms as you go from left to right of the periodic table?
The atomic radius decrease from left to right in the periodic table.
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
How does the size change when an atom forms a cation and when an atom forms an anion?
A metal atom is smaller than the cation formed from it, because the electron(s) lost from a metal atom to form its cations are from the outermost electron shell or energy level of the atom. These electrons increase the size of the atom compared with the cation.
Is the atomic size of francium greater than that of cesium?
The atomic radius of francium and caesium are considered to be equal.
How does atomic size generally go on the periodic table?
Atomic radius generally decreases as you go from left to right in the same period. Atomic radius increases as you go down the same group.
What happens to the size of the atomic radius as you go down the noble gas family?
The atomic radius increase down, from helium to radon.
What happens to the atomic size of the atoms as you go from left to right of the periodic table?
The atomic radius decrease from left to right in the periodic table.
What happens to the size of the atom as you cross the periodic table from group 1 to group 8?
The atomic radius decreases.
How do you tell the size of an elements atomic radius?
The atomic radius of chemical elements is expressed in picometers (pm).
What do you mean by the atomic radius?
Size of a nutral atom
What does atomic radius means?
Atomic Radius means the size of the atoms, the distance from the atomic nucleus to the outermost electron orbital.
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
What is the size of size of mendelevium?
The estimated atomic radius of mendelevium is 194 pm.
What is the size of xenon?
The atomic radius of Xenon is 216 pm.
How does the size change when an atom forms a cation and when an atom forms an anion?
A metal atom is smaller than the cation formed from it, because the electron(s) lost from a metal atom to form its cations are from the outermost electron shell or energy level of the atom. These electrons increase the size of the atom compared with the cation.
What happens to the size of an atom moving from left to right through a period why does this happen?
Atomic radius decreases from left to right due to increase of protons
What happens when a magnesium ion loses an electron?
It becomes a positive ion and atomic radius decreases in size, its divalent ion is more stable though.
