Document Summary

Atomic radius elements that share the same orbital like ca, k differ in the amount of pull created by protons. Since ca has greater amount of protons (we can tell this by the atomic number {z}) The greater the pull on the orbital created by the protons means the smaller the atomic radius. Main group elements s block elements group 2 p block elements group 6. Inner transition elements f block elements lanthanides actinides. Metalloids are conducive of metallic and nonmetallic properties. Some major atomic properties of elements are atomic radius ionization energy electron affinity. Zeffective atomic number and electron shielding of nuclear charge. Atomic radius = radius measures the atoms size. The distance between the nuclei of two identical atoms joined by a covalent bond ex. The distance between the nuclei of two atoms in contact in the crystalline solid metal.
