The atomic radius describes the distance in between the center of the atom and also the external shell the the electrons. Atomic Radius decreases relocating from left to right across the periodic table, throughout a period.Atomic Radius increases moving native the optimal (smallest) to the bottom (biggest) of a column
Beginning native the Largest: Sr, Ca, Mg, Be.Atomic Radius decreases relocating from left come right across the periodic table, across a period.Atomic Radius increases moving from the peak (smallest) to the bottom (biggest) that a column.

You are watching: Which of the following has the smallest radius


Which the the following correctly perform the 5 atoms in bespeak of increasing size (smallest to largest)?a. O b. O c. F d. F e. F
The an initial ionization energies of the elements ________ together you go from left come right across a duration of the periodic table, and also ________ together you go from the bottom come the optimal of a team in the table.a. Increase, increaseb. Increase, decreasec. Decrease, increased. Decrease, decreasee. The very first ionization energies of the facets are fully unpredictable.
________ have actually the lowest an initial ionization energies that the groups listed.a. Noble gasesb. Alkaline earth metalsc. Transition elementsd. Halogense. Alkali metals
e. Alkali metals The ionization power is the lowest. The is in the very first column, the the furthest on the left, ~ above the regular table. The ionization energy increases together it move from the left to the right of the periodic table.
Which equation properly represents the 2nd ionization the phosphorous?a. P-(g)→P2-(g)+e-b. P+(g)→P2+(g)+e-c. P2+(g)→P3+(g)+e-d. P2+(g)+e-→P+(g)e. P(g)→P+(g)+e-
Which equation effectively represents the third ionization that copper?a. Cu(g)→Cu+(g)+e-b. Cu+(g)→Cu2+(g)+e-c. Cu3+(g)+e-→Cu2+(g)d. Cu2+(g)→Cu3+(g)+e-e. Cu2-(g)→Cu3-(g)+e-
d. Cu2+(g)→Cu3+(g)+e-It"s similar to the second ionization question! however instead that a 2+, the a 3+. The equation stays the same, but the X+ will change with the number of ionizations.
