I think it is A. produces the hydrogen ion
Answer: Option (c) is the correct answer.
Explanation:
A positron is denoted as
, a neutron is denoted as
, an electron is denoted as
, and a proton is denoted as
.
Therefore, when
will decay into
this means there occurs decrease in its mass number. Hence, it means a neutron will be releasing during this reaction.
The reaction will be as follows.

Atoms of one element are converted to atoms of another element through transmutation or nuclear transmutation.
A light layer of vacuum grease is applied to the rim of the belljar. Water at room temperature is placed inside and the vacuum pump is then used to evacuate the vessel. When the air pressure is reduced to the vapour pressure of water at room temperature the water will begin to boil.
Answer:
Electrons
Explanation:
The electrons of the outermost energy level determine the energetic stability of the atom and its tendency to form chemical bonds with other atoms to form molecules. Under standard conditions, atoms fill the inner shells first, often resulting in a variable number of electrons in the outermost shell.
