The smaller radius is primarily a result of the magnesium atom having A larger nuclear charge Which of the elements has the least attraction for electrons in a chemical bond? Nitrogen The ability of carbon to attract electrons is Less than that of nitrogen and oxygen As the elements Li to F in period 2 of the Periodic Table are considered in succession, how do the relative electronegativity and the covalent radius of each successive element compare? The relative electronegativity increases, and the atomic radius decreases. This decrease is due to Increasing radius and increasing shielding effect Which sequence correctly places the elements in order of increasing ionization energy? I-Br-Cl-F Compared to the atomic radius of a sodium atom, the atomic radius of a magnesium atom is smaller. Write out the complete electron configuration of titanium, and the valence electron configurations of vanadium, chromium, iron, cobalt, arsenic, and selenium. It has a unique arrangement of rows and columns. Model 1: Atomic radii in groups I and II of the periodic table: 1 Slater, J.C., J. The periodic table is a way of organising the elements which is used by scientists to group elements with similar properties. Which sequence of elements is arranged in order of decreasing atomic radii? Al, Si, P Which list of elements from group 2 on the Periodic Table is arranged in order of increasing atomic radius? Be, Mg, Ca As each successive element in Group 15 of the Periodic Table is considered in order of increasing atomic number, the atomic radius Increases The strength of an atom's attraction for the electrons in a chemical bond is the atom's Electronegativity Which properties are most common in Nonmetals? High ionization energy and high Electronegativity Which Group 17 element has the least attraction for electrons? I Which element in Group 16 has the greatest tendency to gain electrons? O The Group 17 element with the highest electronegativity is Fluorine As the elements of Group 1 on the Periodic Table are considered in order of increasing atomic radius, the ionization energy of each successive element generally Decreases The amount of energy required to remove the outermost electron from a gaseous atom in the ground state is known as First ionization energy Which element is a member of the halogen family? I Which of the following Group 2 elements has the lowest first ionization energy? Ba As elements of Group 1 of the Periodic Table are considered in order from top to bottom, the ionization energy of each successive element decreases. Compare your predictions to the values given in model 1 below.
