What trend in atomic radius occurs as you move down a family on a periodic table?Explain what causes this trend.Group of answer choicesThe atomic radius decreases due to additional energy levels being added to the atom and more electron shielding along with more repulsion and increasing the size of the atomThe atomic radius increases due to additional energy levels being added to the atom and more electron shielding along with more repulsion thus increasing the size of the atomThe atomic radius increases due to less electron shielding down a family and along with more repulsion and increasing the size of the atomThe atomic radius decreases due to additional protons being added along with more electrons in the inner energy levels

Which sentence best explains the observed trend in atomic radius as you move down the periodic table?A.The more neutrons a nucleus has, the larger the atomic radius.B.The more core electrons an atom has, the smaller the atomic radius.C.The more energy levels that are occupied by electrons, the larger the atomic radius.D.The more paired electrons there are, the smaller the atomic radius.

What trend in shielding occurs as you move across a period on a periodic table?Explain what causes this trend.Group of answer choicesThere is an increase in shielding causing the size of the atom to increaseThere is a decrease in the shielding caused the size of the atom to decreaseThere is no additional shielding because there are no additional energy levels when you move left and right on the periodic tableThere is no additional shielding so it causes the size of the atom to get bigger then smaller then bigger again.

What makes the atomic radius change along a period in the periodic table?A.More electrons pair in orbitals, making the atomic radius smaller.B.More electrons in the valence shell make the radius bigger.C.More protons in the nucleus pull the electrons in, making the atomic radius smaller.D.The increased atomic mass makes the atomic radius bigger.

What periodic trend does the atomic radius follow?A.It increases from left to right.B.It decreases from top to bottom.C.It decreases from left to right.D.It stays the same across the table.SUBMITarrow_backPREVIOUS
