Noble gas notation serves as a condensed form of indicating electron configurations. This notation employs the symbol for the preceding noble gas in the electron configuration of an element. For antimony, the noble gas prior is Kr, which means Xe is not used in its electron configuration. Similarly, for radium, the prior noble gas is Rn, whereas, for uranium, it is also Rn. However, for cesium, the preceding noble gas is Xe, thus it is utilized in the noble gas notation for Sb, specifically written as: Cs: [Xe] 6s.
Answer: cesium
A skeletal formula is usually used for organic compounds
The density is 1.03 g/cm³.
Explanation: The density of a substance is calculated with the formula:
1 kg = 1000 g therefore 2.06 kg = 2060 g.
1 L = 1000 cm³ thus 2 L = 2000 cm³.
We now find:
Mass = 2060 g
Volume = 2000 cm³.
Thus, the final answer of density is:
1.03 g/cm³.
