Helium would be the least I think
Answer:
Valinomycin
Explanation:
This antibiotic is acquired from the Streptomyces species cells. Valinomycin is selective to potassium and inhibits sodium ions from entering the cell. This antibiotic allows the potassium ions to move down the electrochemical potential gradient of the lipid membranes.
Don’t Put this as your answer
Solution: We are taking second element from the 4th period.
Element's name is Calcium.
It's symbol is Ca.
It is a metal because it looses its valence electron to form positive ions.
Calcium element lies in the second group of 4th period. The elements belonging to the second group are known as alkaline earth metals.
Atomic Number of Calcium = 20
Atomic number = Number of protons = Number of electrons
therefore,
Number of electrons and protons = 20
Atomic Mass of Calcium = 40
Atomic Mass = Number of neutrons + Number of proton
bu substituting the values of atomic mass and number of prtons, neutrons can be calculated
Number of neutrons = 20.
The heat capacity of a defined system is the amount of heat (usually expressed in calories, kilocalories, or joules) needed to raise the system's temperature by one degree (usually expressed in Celsius or Kelvin). It is expressed in units of thermal energy per degree temperature. To aid in the analysis of systems having certain specific dimensions, molar heat capacity and specific heat capacity can be used. To measure the heat capacity of a reaction, a calorimeter must be used. Bomb calorimeters are used for constant volume heat capacities, although a coffee-cup calorimeter is sufficient for a constant pressure heat capacity.
