number. You will see subshells S, P, and D on the chart (24). The subshell that the valence electron occupies dictates the position of the element on the periodic table. The S subshell occupies groups 1 and 2, the D subshell is all of the transition metals, and the P subshell occupies groups 13-18. The D subshell is irregular in that it will always have a three in front of it, but the numbers in front of the other subshells will change based on what shell they are in. The three is there to show…

Pre-Lab Questions 1. What are the steps of the scientific method? Briefly explain each. • The steps of the scientific method are observation, define problem, construct a hypothesis, test the experiment/ gather evidence, and draw a conclusion. Observation is the procedure of collecting information about events and processes carefully. It involves with seeing and hearing. Defining the problem is when you identify a conflict that requires a solution to be solved. A hypothesis is a proposed…

boreholes, glacier lengths, and pollen remains to obverse what could cause climate change (Rye, et. al., 2013). From these studies they have found three natural-induced process that have influenced global climate change which include changes in the Earth 's distance from the sun due a changing orbit (also known as Milankovitch cycles), changes in the Sun 's power and intensity ,and volcanic eruptions (Rye, et. al., 2013). There three factors, are naturally occurring or Non-man made phenomenon…
