3d10 4p6 5s2 4d1 Noble Gas form: Kr 4d5 5s1 QUESTION 3 Compare the relative differences in strength that results from ionic‚ covalent and metallic boding. There are two types of bond‚ the strong bonds and the weak bonds. Covalent bond is part of strong bond and it has the highest strength among the strong bond. Ionic bond is part of the strong bond but the strength of ionic bond is a medium strong bond. The metallic bond is also part of the strong bond but the strength of the metallic bond is

Learning Goal: To understand how the scientific method can be used to search for explanations of nature. The scientific method is a procedure used to search for explanations of nature. The scientific method consists of making observations‚ formulating hypotheses‚ designing and carrying out experiments‚ and repeating this cycle. Observations can be either quantitative or qualitative. Quantitative observations are measurements consisting of both numbers and units‚ such as the observation that ice melts
