There are 2 different types of elements is s-block.
1. Alkali earths metals.
2. Alkaline earths metals.
2 Exceptions are Hydrogen and helium gas.
Examples: Sodium, potassium, francium, beryllium, magnesium... etc
"lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air)
I would choose count of electron shells and count of valence electrons. The electron configuration of each element is fixed and can be used to determine the element's identity. By counting the electron shells, you can have an idea which part of the periodic table the mystery element lies, and by determining the number of valence electrons (outermost shell), you can pinpoint the exact identity of the mystery element.
Hey there!
Volume in mL :
1.68 L * 1000 => 1680 mL
Density = 0.921 g/mL
Therefore:
Mass = density * Volume
Mass = 0.921 * 1680
Mass = 1547.28 g
