Answer:
P = 2,8,3
q = 2,8,6
Explanation:
Because the first shell contain 2 electron and the 2nd contain 8 electron and the last shell contain the electron which is left
Answer: Relative humidity
Explanation:
Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor has higher relative humidity in cool air than in warm air. A related parameter to that regard is that of dew point.
Answer: Difference in properties of these two compounds are because one compound is covalent and the other one is ionic.
Explanation: LiCl is an inorganic compound having high electronegativity difference between the two elements and hence, is termed as an ionic compound.
is a organic compound formed by the sharing of electrons between the elements, hence is termed as a covalent compound.
Hence, the properties are different because one of the compound is covalent and other is ionic.
An unscientific device for locating oil or minerals; a divining rod.
Answer:
25
Explanation:
Isotopes of an element are the same element with different mass numbers but the same atomic number or the number of protons.
we know that in a balanced atom
Number of electrons = Number of protons = Atomic number
Atomic number (z) of manganese = 25
For Mn+5, the number of protons remains the same = 25
However, the number of electrons on Mn+5 = 21
