The mass is written as a superscript and the charge is written as a subscript in the isotope notation of element X as follows .
The isotope notation may also be called the nuclear notation of an element. It helps us to identify what element is represented. It usually comprises of the atomic mass of the element written as a superscript and then the atomic number or charge written as a subscript.
In this case, we have an element with an mass of 292 amu and charge of 119. In this case, the isotope notation of element X is .

“It can hold two electrons”
Answer:
You'll experience a grater deviation
Explanation:
<em>You'll experience a greater deviation in your measurements, meaning your measures will have a bigger difference between them, and the greater these deviations the less accurate will be the measuring.</em> This happens mainly because you're not replicating the measurement with the exact same conditions, in one of them you'll have an extra mass from the water.
I hope you find this information useful and interesting! Good luck!
Answer: The element shown in the image is Helium (He).
Explanation: We are given a image of an atom having protons, neutrons and electrons.
Number of protons as shown in image = 2
Number of neutrons as shown in image = 2
Number of electron as shown in image = 2
Atomic number = Number of protons = Number of electrons
Atomic number of the element = 2
Atomic Mass = Number of protons + Number of neutrons
Atomic mass = 2 + 2 = 4
The element having Atomic number = 2 and mass number = 4 is Helium.
Element =
