Answer:
Element Lithium
Explanation:
The element with the highest second ionization energy is lithium. It belongs to the alkaline metal group I.e group one metals
It has the highest second ionization energy because it is very difficult to remove the electron from the 1s orbital.
Its atomic number is 3. The electronic configuration is 1s2 2S1
Answer:
D) 6
Explanation:
The balanced equation would be:
6Li + N2 -> 2Li3N
- The density of the mineral fragment is
(20.47 g/cm3).
- Density can be regarded as<em> ratio of mass to the volume </em>of the object.
Density = (mass/ volume)
Given:
volume of mineral fragments= 2.57 cm3
mass = 52.6 g
density of the mineral fragment = (52.6/2.57)
= 20.47 g/cm3
- Therefore, density of the mineral fragment is (20.47 g/cm3)
