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 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

Deduce which of the following periodic trends increases across a period in the periodic table (from left to right).I.   Electron shieldingII.  Ionisation energyIII. Nuclear chargeIV. Atomic radius

While moving in a period from left to right,Atomic size decreasesNuclear charge increasesI.E increasesAll of the above

Which of the following correctly outlines why electronegativity increases across a period?The level of electron shielding increases There are more electrons and more repulsion between electronsThe atomic radius decreasesThere is an increase in nuclear charge and a decrease in the atomic radiusReport feedback

Deduce which trends are seen as you move down a group in the periodic table.I.   increase ionic radiusII.  increase in atomic radiusIII. increase in ionisation energyIV. increase in electronegativity
