Question

What does the following element description actually mean? (File below)

A. It means it is an aluminum atom with 27 protons and 13 electrons.

B. It means it is an aluminum atom with 27 electrons and 13 protons.

C. It means it is an aluminum atom with 13 neutrons and 14 protons.

D. It means it is an aluminum atom with 13 protons and 14 neutrons.

E. None of the above.

Answer 1

Step-by-step explanation:

This is an aluminum atom with 13 proton because from what henry said in the year 1914 he said that the number of protons of an element is equal to the number of electrons for an neutral atom..an you expect the number of electrons to be the atomic number.( The number that is used to locate the elements in the periodic table (1869).

And the number of neutron is 13 because form the mass number of the elements and we no that the mass number of an element is the sum of the proton and the neutron..MN=P + N.....so when 13 is substracted from 27 the answer is 14. So the answer is option D.
