QuestionAnswer
What happens to ionization energy as you move down the groups? it decreases
What happens to atomic radii as you move down the groups? it increases
What happens to metallic character as you move down the group? it increases
What happens to electronegativity as you move down the group it decreases
What happens to ionization energy as you move across the periods? it increases
What happens to atomic radii as you move across the periods? it decreases
What happens to metallic character as you move across the periods? it decreases
What happens to electronegativity as you move across the periods? it increases
Why does atomic radii move in that way down a group? as you move down, more energy levels are added and the more atoms in the center, the more attracted the electrons will become
Why does metallic character move in that way down a group? as atomic radii increases the electrons become farther apart from the protons making them easier to lose
Why does ionization energy move in that way down a group? as radii increases the valence electron and nucleus attraction lessens and less energy is needed
Why does electronegativity move in that way down a group? as radii increases it is harder for protons in the nucleus to attract electrons in other atoms
Why does atomic radii move in that way across a period? electrons are pulled closer together (because an atom is mostly empty space) due to each new successive element added
Why does metallic character move in that way across a period? as radii decreases, it becomes harder to lose electrons
Why does ionization energy move in that way across a period? as radii decreases , the attraction between valence electrons and the nucleus is strengthened and more energy is needed
Why does electronegativity move in that way across a period? as radii decreases, it becomes easier for protons in the nucleus to attract electrons of other atoms
