Scientists believe that interactions between atoms depend mostly on the arrangement of the outermost electrons in each atom. This theory is MOST supported by the observation of similar reactions among elements — with a similar atomic mass
with a similar atomic number
in a group (column) of the periodic table
in a period (row) of the periodic table

What is an example of a physical property?

Which ocean zone has the most abundant primary producer and why a) the abyssopelagic zone ,du to the absence of light and cold water temperatureb) the bathypelagic zone, due to the absence of light and cold water temperaturec) the mesopelagic zone ,due to uts high light availability and warm water temperature d) the epipelagic zone,due to its high light availability and warm water temperature

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
