The periodic table contains groups and periods that include the elements. For group 1 metal lithium is least likely to lose an electron.
<h3>What are group 1 metals?</h3>
Group 1 metals are the alkali metals that include, Li, Na, K, Rb, and Cs. They show the property exhibited by the metals. The chemical trends of group 1 show that cesium loses an electron more easily than the other elements.
When going down the group the tendency to lose electrons increases as the atomic radius increases. The electron gets far away from the nucleus making it easy to get removed.
Therefore, lithium being the first element of the group has the smallest radii and is least likely to lose an electron.

Answer:
Explanation:
= Initial pressure = 200 kPa
= Final pressure
= Initial temperature = 
= Final temperature = 
We have the relation
The pressure that would be exerted after the temperature change is .
Energy would be the correct answer
Answer:
PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.
Newer technology combines PET and CT into one scanner, known as PET/CT. PET/CT shows particular promise in the diagnosis and treatment of lung cancer, evaluating epilepsy, Alzheimer's disease and coronary artery disease.
