True false questions using periodic trends?

Within a family, elements with higher atomic numbers have atoms of larger radius because the valance electrons are in higher principal energy levels.





Within a family, elements with lower atomic numbers have lower electronegativity because the atoms have lower effective nuclear charge.





Within a family, elements with lower atomic numbers require more energy to remove an electron from the atom, because the atoms have higher effective nuclear charge.





Within a period, elements with higher atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels.





Within a period, elements with lower atomic numbers require less energy to remove an electron from the atom because the atoms have lower effective nuclear charge.





Within a period, elements with higher atomic numbers have atoms of smaller radius because the valance electrons are in higher principal energy levels. True false questions using periodic trends?
true - increasing electrons = size (radius) larger





false - low-electron element triggers higher electronegativity; nucleus attracts valence electron even stronger





true - the smaller the atomic number, nucleus attracts more hence increasing ionization energy (to remove an electron at valence)





false - across period, increasing atomic numbers = size smaller; attraction of nucleus towards valence electron higher - higher ionization energy





false - lower atomic number element requires more energy to remove an electron at its valence due to strong attraction of nucleus - but across period (left to right) atomic size decreases, larger IE but lower atomic number element requires more energy too to remove an electron from its valency





true - the more atomic numbers in an atom, the smaller the size (radius) - across periodTrue false questions using periodic trends?
1. true


2.false , atoms with increasing at no.hav lower electonegetivity


3.true


4.false it increases with inc in atomic no.(atomic radius decreases)


5.false itis not linearly varying


6.true
