Part A Which of the following statements best explains this observation? O The group 4A elements have unusually large atomic radi. O The group 4A elements have much higher first ionization energies than their neighbors in groups 3A and 5A. O The group 4A elements are easier to vaporize than are the group 3A and 5A elements. O The addition of an electron to a group 4A element leads to a half-filled np outer electron configuration. Submit Request Answer Provide Feedback

Enter the ground state electron configuration on the right of each element listed below (you may use the preceding Noble gas core):

1, eight electrons with n = = 2, A neutral atom has two electrons with n = and seven electrons with n = 3. Assuming this element is in its ground state, supply the following information: a. atomic number Atomic number = b. total number of s electrons s electron(s) c. total number of p electrons p electron(s) d. total number of d electrons d electron(s) e. Is the element a metal, metalloid, or nonmetal? metal O metalloid nonmetal

For the abbreviated electron configuration for the element with 48 protons, which noble gas would you use as a start?
