Answer:
For the purposes of your question, we can think of speed and velocity as being the same thing. Therefore, the potential energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the potential energy will increase by a factor of four.
Answer:
if you add a neutron to lithium-7 it becomes a compound nucleus of lithium-8
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
Using spectral analysis of the Sun's emission spectra.
