Answer is A
All elements on the periodic table have a different number of protons that can be represented by its atomic number
Answer:
Magnesium
Explanation:
When an atom loses are gain the electrons ions are formed.
There are two types of ions.
Anion
Cation
1 = Anion
It is formed when an atom gain the electrons. when atom gain electron negative charge is created on atom. For example.
X + e⁻ → X⁻
2= Cation
It is formed when an atom loses the electrons. when atom lose electron positive charge is created on atom. For example.
X → X⁺ + e⁻
There are seven valance electrons in iodine. To complete the octet it gain one electron and form anion.
Sulfur has six valance electrons it gain two electrons to complete the octet and form anion.
Phosphorus has five valance electrons it gain three electrons two complete the octet and form anion.
Magnesium has two valance electrons it loses two electron to complete the octet and form cation.

Answer:
1.27 atm.
Explanation:
The following data were obtained from the question:
Pressure (P) in torr = 968 torr
Pressure (P) in atm =...?
Thus, we can convert from torr to atm by doing the following:
Recall:
760 torr = 1 atm
Therefore,
968 torr = 968/760 = 1.27 atm
Therefore, 968 torr is equivalent to 1.27 atm.
