Answer:
Argon's atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
Explanation:
Atoms are the most basic unit of matter that makes up elements. Atoms are composed of electrons orbiting neutrons and protons surrounding a nucleus.
The atomic number is defined as the number of protons in an atom, while the atomic mass is the number of protons and neutrons.
The element Argon, Ar is a noble gas, that exists in a gaseous, inert, state at temperature. Its atoms have 18 protons, 22 neutrons in its nucleus, orbited by 18 electrons- its atomic mass= P 18 +N 22.
There are 8 valence electrons in its outer shell, thus:
- Ar is not very reactive, as it does not require electron sharing in atomic bonding.
- It shows low conductivity, as there are no free electrons
Explanation:
Photosystems are the practical components for photosynthesis, well-defined by a specific stain association and connotation patterns, whose work is the absorption and allocation of light energy, which suggests transfer of electrons. Physically, photosystems are initiate in the thylakoid membranes. A photosystem consists of a light-harvesting complex and a reaction center. Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. Photosystem I or PS I and Photosystem II or PS II are the protein-mediated complex, and the main aim is to produce energy (ATP and
), which is used in Calvin cycle, the PSI uses light energy to convert NADP+ to
.
Answer:
C. a chemical treatment.
Explanation:
In this case we would be talking about a chemical treatment, since the application of an artificial compound is made, and it is not clarified that it was "ecofriendly".
On the other hand, the question clarifies that the farmer is suffering from the plague. This indicates that he is not preventing it (Integrated pest management), he is treating it.
Finally, it should not be considered as an agronomic treatment, since no real modifications are being made to the way the field is managed.
