What is the difference between two neutral atoms represented by the symbols59 5927 28Co and Ni ?A. The number of neutrons only.B. The number of protons and electrons only.C. The number of protons and neutrons only.D. The number of protons, neutrons and electrons

No answer

The difference between two neutral atoms represented by the symbols 59 27Co and 59 28Ni is the number of protons and electrons only.

Here's why:

1. The number before the symbol (59 in this case) represents the atomic mass number, which is the sum of protons and neutrons in the nucleus. Since both atoms have 59 as their atomic mass number, they have the same number of protons and neutrons combined.

2. The number below the symbol (27 for Co and 28 for Ni) represents the atomic number, which is the number of protons in the nucleus. Since these numbers

The difference between two neutral atoms represented by the symbols 59 27Co and 59 28Ni is:

A. The number of neutrons only. B. The number of protons and electrons only. C. The number of protons and neutrons only. D. The number of protons, neutrons and electrons.

The answer is B. The number of protons and electrons only.

Here's why:

The number above the element symbol (59) is the atomic mass number, which is the sum of protons and neutrons in the nucleus. Since these numbers are the same for both atoms (59), the number of neutrons is the same in both atoms.

The number below the element symbol is the atomic number, which represents the number of protons in the nucleus. For 27Co (Cobalt), the atomic number is 27, meaning it has 27 protons. For 28Ni (Nickel), the atomic number is 28, meaning it has 28 protons. Therefore, the number of protons is different.

In a neutral atom, the number of protons is equal to the number of electrons. Therefore, since the number of protons is different, the number of electrons is also different.

So, the difference between these two atoms is the number of protons and electrons only.
