Write the name (not the symbol) (d) Two elements for which a diagonal relationship (to each other) is observed are and Write the names (not the symbols) (e) An atom that has no lone pairs and is bonded to six other atoms has molecular...
Question 20 In which of the following pairs is the first atom atomic radius larger than the second atom? O a. K. Ca O b.Ne. Ar Oc. ci, P O d.o. S
4. Answer the following questions about periodic trends. a) Which element is larger, As or Mc? Explain (do not just state a trend) b) Which element has the lower first ionization energy, Ca or Br? Explain (do not just state a trend). c) Explain the relationship between atomic size (radius) and ionization energy.

For each of the following pairs of atoms or ions, state which you expect to have the larger radius. (a) Se or Ca (b) Ca or Ca2+ (c) Ca2+ or Ar (d) F or I (e) Ar or S2-
I just dont know if these are right. Any help is much appreciated! Compare the size of I and I: I has the same number of protons and more electrons compared to I. For this reason, l'experiences a lower Zeff which makes the ion larger in size compared to l. Question 10 0.15 pts Compare the size of Ca2+ and K+: Ca2+ has more protons and the same number of electrons compared to K+. For this reason, Ca2+ experiences a...
Question 9 Which of these statements is false? An anion is always larger than its parent neutral atom. The first electron affinity is always a large negative value. First ionization energy decreases in going down a column (group). Second ionization energies are always larger than first ionization energies. Atomic size decreases in going from left to right across a row (period).
explanation needed thank u . Which element has a larger SECOND ionization energy, Ca or K? Explain.
