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
Answer:
If the producer population decreased, the size of the hervibores population will diminish.
Explanation:
Producer population refers to autotrophic organisms (plants for example). These organisms are the nutrition source for primary consumers (like hervibores). So if the nutrition source decreased, the population size of hervibores will decreased too.
Answer:
D. S and X
Explanation:
The pair that is at the same level of structural organization is S and X.
S is the brain of human
X is the leaf of plant.
Both the brain and the leaf are in the organ level of organization. The brain is an organ in human body which carries out most activities in the body. It controls all functions of the body and also interprets information from the outside world. The brain is the seat of intelligence, emotion, creativity and memory.
The leaf in plants is a collection of tissues. It enables photosynthesis to occur. The leaf traps sunlight and carbon dioxide which are used during photosynthesis to manufacture food for plants.
