Remember. Given the following groups, what is the maximum possible order for an element for Ca. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. Sometimes the halogens are considered to be a particular set of nonmetals. The atomic radii of representative elements decrease from left to right across a peri od (horizontal row in the periodic table). In group 15, as elsewhere in the p block, we see large differences between the lightest element (N) and its congeners in size, ionization energy, electron affinity, and electronegativity (Table \(\PageIndex{1}\)).

As one moves from down ( ↓ ) a group on the periodic table, the atomic radius of the elements encountered tends to: ? Which of the following places the elements in the correct order of increasing first ionization energy? This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. Group 8 (noble gases) have the highest first ionization energy because they are already stable and don't want to lose any electrons. It has three isotopes, namely, 12 C, 13 C, and 14 C where 14 C is radioactive. Transition elements have larger atomic radii than the preceding IA and IIA elements in the same period because transition elements have electrons in their d orbitals. Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).They are harder and less reactive than the alkali metals of Group 1A.
