groups and periods

Question 1

down a group

Answer 1

electronegativity decreases (shells increase)
ionisation energy decreases ( shells increase)
atomic radius increase ( shells )
core charge remains constant

Question 2

across a period

Answer 2

electronegativity increases (core charge increases)
ionisation increases ( core charge increase more strongly attracted to nuclear)
atomic radius decreases (core charge increases pulling electrons in closer)
core charge increase
