best answer is C. your welcome
Hello there!
Hydrogen has one proton because the number of protons in an atom is equal to the atomic number of the element. S ince hydrogen's atomic number is 1, it has one proton.
I hope that's help !
Answer:1
Explanation:
hydrogen only has 1
b. climax
c. external conflict
d. internal conflict
first ionization energy
(1) decreases
(2) increases
(3) decreases, then increases
(4) increases, then decreases
Answer: The first ionization energy for the first five elements of Group 15 decreases.
Explanation:
Ionization energy is defined as the energy required to remove an electron from the outermost shell of an isolated gaseous atom. It is represented as
Ionization energy decreases as we move down the group. This happens because the number of shells increases as we move down the group. The electrons are added in the new shell around the nucleus.
This results in the shielding of outermost electrons more from the inner ones, which decreases the attraction between the outermost electrons and the nucleus. Hence, the removal of electron from the outermost shell becomes easy and requires less energy.
Hence, the first ionization energy for the first five elements of Group 15 decreases.
evaporation
condensation
transpiration
Answer : The correct option is, evaporation
Explanation :
Evaporation : It is a type of process in which the phase changes from liquid state to gaseous state at constant temperature.
Condensation : It is a type of process in which the phase changes from gaseous state to liquid state at constant temperature.
Precipitation : It is a type of process in which the solid is formed when the reaction occurs in liquid solution.
Transpiration : It is a process in which the water moves from roots of the plant to the small pores. That means the movement of water through the plant.
When water changing from a liquid to a gas is an evaporation.
Hence, the correct option is, evaporation.
Answer:
The answer is evaporation
B.number
C.mass
D.direction
