Me i beg you i really need elements on the periodic table appear together in regions based on the energy sub-level that contains their outermost valence electrons. what are these regions called? families blocks main-group elements transition elements mendeleev's periodic law has been restated to say that when the elements are arranged in order of increasing atomic number, there is a periodic pattern in their chemical and physical properties. true false in 1894, william ramsey discovered the first of several non-reactive elements. which group of elements did ramsey discover that would alter the structure of the periodic table? the transition metals the noble gases the halogens the alkali metals which of the following elements is man-made? platinum technetium radon cesium what is the name of the group (family) that includes the elements radium, strontium, and magnesium? noble gases metals alkaline earth metals alkali metals an element's atomic number is an indicator of its atom's: number of protons number of neutrons charge weight an atom of oxygen contains 8 protons, 8 electrons, and 16 neutrons. true false which of the following is not true of electronegativity? generally increases as atomic radius decreases within a period generally decreases as atomic number increases within a period generally decreases as the principal energy level increases within a group generally increases as atomic radius decreases within a group which of the following elements possesses the most valence electrons? argon fluorine helium plutonium how many dots should be drawn around the symbol, c, to create the lewis dot structure for a carbon atom? two four six eight to achieve an octet in the valence energy level, a nitrogen atom will lose five electrons. true false to achieve an octet in the valence energy level, a sulfur atom will become a cation. true false
