ASAP! two different atoms have nine protons each and the same mass. However one is neutral while the other has a negative charge. Describe what each atomic structure could be, listing the possible number and location of all subatomic particles.

Two different atoms have 9 number of protons.

One atom is neutral atom that means it has 9 number of electrons.

One atom has a positive charge that means it has 8 number of electrons.

The atom will be fluorine (F) because it has the 9 number of protons.

And the atomic mass of fluorine is 19.

As per given question, both the atoms have the same mass that means both the atoms has 10 number of neutrons.

Number of neutrons = Atomic mass - Atomic number = 19 - 9 = 10 neutrons

Therefore, the two different atoms could be, _9F and _9F^+ and the location of all subatomic particles is that the protons and neutrons are present in the nucleus and the electrons are present around the nucleus.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.

it should be all of them because it asks if you included all of those in your answer
