Hey Guys. I got this question with these 6 elements in this table Silver = Metal Helium = Noble Gas Hydrogen = Non Metal Chlorine = Halogen Lead = Metal Sodium = Alkali Metal Now the question says Which of these are metals? I answered: Silver, Lead But I am wondering about Sodium can it be in the answer? Also another question states: Comparing the Density of the metals and non metals, Which element represents an anomaly? Why? Density (g mL^-1) Silver = 10.5 Helium = 0.00017 Hydrogen = 0.00008 Chlorine = 0.00291 Lead = 11.3 Sodium = 0.97 This question I dont clearly understand and I hope someone can help me!!
