Explanation:
Atomic Number = Number of protons
Mass Number = Number of protons + Number of neutrons
Isotopes are simply atoms of an element with the same number of protons and different number of neutrons.
First Isotope -- 238U
Number of neutrons = Mass Number - Atomic Number
Number of neutrons = 238 - 92 = 146
Second Isotope -- 235U
Number of neutrons = Mass Number - Atomic Number
Number of neutrons = 235 - 92 = 143
Answer:
pioneer species. because they are flower like species
Answer:
Freezing
Melting
Condensation
Evaporation
Sublimation
Deposition
Explanation:
From the diagram,
(1) Liquid⇒Solid (Freezing)
Freezing: This is the process by through which a substance change from liquid to solid.
(2) Solid⇒Liquid (Melting)
Melting: This is a process through which a substance change from solid to liquid
(3) Liquid⇒gas (Evaporation)
Evaporation: This is a process through which a substance change from liquid to gas.
(4) gas⇒Liquid (Condensation)
Condensation: This is a process through which a substance change from gas to liquid
(5) Solid⇒gas (Sublimation)
Sublimation: this is a process through which a subtance change from solid to gas
(6) gas⇒solid (Deposition)
Deposition: This is a process through which gas transform into solid.
