WebNov 20, 2024 · Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation. 1156.1 K. 12. Mg. ... In the periodic table of elements, the element with the lowest boiling point is helium. Both the boiling points of rhenium and ... WebOct 1, 2010 · Boiling points are a measure of intermolecular forces. The intermolecular forces increase with increasing polarization of bonds. The strength of intermolecular forces (and therefore impact on boiling points) is ionic > hydrogen bonding > dipole dipole > dispersion Boiling point increases with molecular weight, and with surface area.

Melting points and boiling points of Group 1 elements? - Answers
WebExpert Answer Answer 1) 1. 0.18m MgI2 : B second highest boiling point 2. 0.19m Fe (NO3)2 : A highest boiling point 3. 0.16m CrCl2 : D Lowest boiling point 4. 0.50m sucrose (nonelectrolyte) : C Third highest boiling point 2) 1. 0.13m AlBr3 : B second lowest free … View the full answer Previous question Next question WebMar 2, 2024 · Answer: Potassium Explanation: In group one of the periodic table both the melting and the boiling points usually decrease down the group. Now, down the group, it's lithium that comes first, then sodium, then potassium. Thus, among the 3, potassium is furthermost down the group by virtue of the factor it has the highest atomic number. screen recording windows 10 gaming
Solved Which of the following aqueous solutions should have - Chegg
WebQuestion: Which of these solutions 0.1 m NaCl, 0.15 m glucose, 0.1 m CaCl2 would have: The highest vapor pressure The lowest boiling point 0.15 m glucose, 0.1 m CaCl2 0.1 m CaCl2, 0.1 m CaCl2 0.15 m glucose, 0.15 m glucose 0.1 m CaCl2, 0.15 m glucose 0.1 m NaCl, 0.1 m CaCl2 WebJul 10, 2015 · This explains why group 1 metals such as sodium have quite low melting/boiling points since the metal would be composed of electrons delocalized in a M + lattice. Going towards group 2 and group 3 elements, one can expect to find a M 2 + and M 3 + lattice, and so on. WebThe zero point is different: temperature (K) = temperature (°C) + 273.15. Thus, the melting point of water is = 0°C = 273.15 K and the boiling point of water is = 100°C = 373.15 K. … screen recording video on laptop
