Verified answer

Answer:

The correct representation for an element 'X' with 15 electrons and sixteen neutrons would be:

Atomic number: 15

Element symbol: P (Phosphorus)

Number of protons: 15

Number of neutrons: 16

Number of electrons: 15

The atomic number represents the number of protons in the nucleus of an atom, which determines the element. In this case, the atomic number is 15, which corresponds to the element phosphorus (symbol: P). The number of electrons is equal to the number of protons, so there are 15 electrons. The number of neutrons can be calculated by subtracting the atomic number from the total mass number. In this case, the number of neutrons is 16.

Explanation:

The correct representation of the element 'X' would be:

Atomic number (number of protons) = 15

Number of electrons = 15

Number of neutrons = 16

Therefore, the atomic symbol for element 'X' would be:

15

P

X
