Answer:
Option A. ¹¹ ₅B⁰
Explanation:
The following data were obtained from the question:
Proton = 5
Neutron = 6
Electron = 5
Symbol of element =..?
Next, we shall determine the atomic number of the element. This can be obtained as follow:
The atomic number of an element is simply the number of protons in the atom of the element. Mathematically, it is expressed as:
Atomic number = proton number
Proton = 5
Atomic number = proton number = 5
Therefore,
Atomic number = 5
Next, we shall determine the mass number of the element. This can be obtained as follow:
Proton = 5
Neutron = 6
Mass number =.?
Mass number = Proton + Neutron
Mass number = 5 + 6
Mass number = 11
Next we shall determine the name of the element. This can be obtained as follow:
Since no two elements have the same atomic number, the element is therefore called boron (B). This is true because only boron (B) has atomic number of 5 in the periodic table.
Next, we shall determine the charge of the element. This can be obtained as follow:
Proton = 5
Electron = 5
Charge =?
Charge = proton – electron
Charge = 5 – 5
Charge = 0
Therefore, the charge on the element is zero.
Finally, we shall determine the symbol of the element as follow:
Mass number = 11
Atomic number = 5
Charge = 0
Name of element = Boron
Symbol = ¹¹ ₅B⁰
