Answer:
B is the correct model of beryllium.
Explanation:
An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.
All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom has 6 protons than it must have 6 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.
For example in case of beryllium:
The atomic number of beryllium is 4.
The atomic mass is 9 amu.
Number protons = 4
Number of electrons = 4
Number of neutrons = 9-4 = 5
So b is correct answer because 5 neutrons and 4 protons are present with in nucleus while 4 electrons are present out side.
I believe your answer is B.
A cold front can cause heavy rain, thunder, and lightning.
An occluded front can cause light to heavy precipitation that may last several days.
A warm front brings drizzly weather.

the area. The scientist wants to conduct a study that will measure the change in the
local mosquito population over a period of three months. Which research method
would give the scientist the best data for conducting his study?
A. a three-month case study observing the behavior of animals that depend on
mosquitoes for food
B. a survey asking residents about their observations of the local mosquito
population
C. a collection device in the area that counts the number of mosquitoes caught
weekly
D. a controlled lab experiment with mosquitoes that limits watercolor the
experimental group
Answer: (C.) a collection device in the area that counts the number of mosquitoes caught
weekly
Explanation: I took the test :D
The most suitable research method for measuring a change in the mosquito population due to construction would be 'a collection device in the area that counts the number of mosquitoes caught weekly'. This method provides quantifiable, reliable data over the three-month study period.
To thoroughly study the change in the local mosquito population due to the construction, the most suitable research method for the scientist would be to use 'a collection device in the area that counts the number of mosquitoes caught weekly' (option C). This method would provide direct, quantifiable data about the mosquito population, showing changes on a weekly basis over the three-month study period.
A case study (option A) would not provide direct data about the mosquito population. Instead, it would provide indirect observations through the behavior changes of animals that prey on mosquitoes. Similarly, a survey (option B) relies on residents' subjective observations, which may not be reliable or accurate. Finally, a controlled lab experiment (option D) does not account for the plethora of variables present in a natural environment, thus limiting its effectiveness in this situation.
