trends in periodic table

Question 1

electrostatic attraction

Answer 1

related to distance the valence electrons are from the nucleus

strength of attraction of protons and electrons

Question 2

shielding effect

Answer 2

related to number of inner shell electrons, shield the effect of the protons from valence electrons.

correlates to number of inner electron shells and attraction of valence electrons to nucleus

Question 3

core charge

Answer 3

how defective the charge of the nucleus is at holding the valence electrons in

increases going towards noble gases

Question 4

atomic radii

Answer 4

increase going down

decrease going right

Question 5

electronegativity

Answer 5

ability of atom to attract electron
increases going right
decrease going down as electron is further from nucleus so it is harder to attract

Question 6

ionisation energy

Answer 6

energy required to remove loosely bound electron

increases towards right
decreases going down because valence shell is further away making it easier to lose electrons

Question 7

electron affinity

Answer 7

ability to accept electron and from a negative ion

Question 8

metallic character

Answer 8

set of properties associated with metals

depends on ability to lose valence electrons

decrease going right
increase going down
