I need help please! :( can someone answer the question of “How is continental lithosphere different from oceanic lithosphere?”

Ahypothrticalax type of ceramic material is known to have a density of 2.10 g/cm3 and a unit cell of cubic symmetry with a cell edge length of 0.57 nm. the atomic weights of the a and x elements are 28.5and 30.0 g/mol, respectively. on the basis of this information, which of the following crystal structures is (are) possible for this material: sodium chloride, cesium chloride, or zinc blende

The p sub shell can hold up to 8 electrons in an atom. true or false?

Which of the following elements would you expect to have the lowest ionization energy value? fluorine, lithium, neon, nitrogen
