Read the two passages. Silicon is an element that is directly below carbon on the periodic table. Silicon can form bonds similar to carbon. Silicon-silicon single bonds require 222 kJ/mol of energy to break. Based on the statements, how much energy would it take to break a carbon-carbon single bond?

astronomers such as edwin hubble.

what does the table look like

i have no clue hope you find the answer

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
