Answer

Explanation:

Step1: Recall atomic - related definitions

The atomic number ((Z)) is equal to the number of protons ((P)) and for a neutral atom, the number of electrons ((E)). The mass number ((A)) is the sum of protons and neutrons ((N)), so (N=A - P).

Step2: For Li (Atomic # = 3, Mass # = 7)

The number of protons (P = 3) (since atomic number = number of protons). The number of neutrons (N=A - P=7 - 3 = 4). The number of electrons (E = 3) (for a neutral atom).

Step3: For Ne (Atomic # = 10, Mass # = 20)

The number of protons (P = 10). The number of neutrons (N=A - P=20 - 10 = 10). The number of electrons (E = 10).

Step4: For Mg (Atomic # = 12, Mass # = 24)

The number of protons (P = 12). The number of neutrons (N=A - P=24 - 12 = 12). The number of electrons (E = 12).

Step5: For Cl (Atomic # = 17, Mass # = 35)

The number of protons (P = 17). The number of neutrons (N=A - P=35 - 17 = 18). The number of electrons (E = 17).

Step6: For He (Atomic # = 2, Mass # = 4)

The number of protons (P = 2). The number of neutrons (N=A - P=4 - 2 = 2). The number of electrons (E = 2).

Step7: For Si (Atomic # = 14, Mass # = 28)

The number of protons (P = 14). The number of neutrons (N=A - P=28 - 14 = 14). The number of electrons (E = 14).

Answer:

Element # of P # of N # of E
Li 3 4 3
Ne 10 10 10
Mg 12 12 12
Cl 17 18 17
He 2 2 2
Si 14 14 14
