How is an atom's atomic number related to its number of protons and electrons?

Answer 1

Atoms gain or lose electrons so they have the same amount of electrons as the nearest noble gas. If you came across this question in the Science 10 textbook, page 39, the answer is found on page 35, bottom paragraph, 4 sentences in. I do have to say the question isn't well written.

Answer 2

The atomic number of an atom is the number of protons in the nucleus of that atom.

The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons.

The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.

Answer 3

Atomic Number is the amount of electrons in an atom, it is also the amount of protons in the nucleus of an atom.

Example:

Oxygen (O) has the atomic number, 8. Which means that there are 8 protons in the nucleus of an oxygen atom and also 8 electrons that surround the nucleus of an oxygen atom.

Answer 4

Since the atomic number of an element is actually the number of protons in an element and since elements are neutral, the number of protons and electrons are equal meaning the atomic number also gives the number of electrons.

Answer 5

the electrons increase as they go to the right. the electrons in the energy is the same as the atomic number.

Group 1 (I) (alkali metals)1Group 2 (II) (alkaline earth metals)2Groups 3-12 (transition metals)use d electron count instead

Group 13 (III) (boron group)3Group 14 (IV) (carbon group)4Group 15 (V) (nitrogen group)5Group 16 (VI) (chalcogens)6Group 17 (VII) (halogens)7Group 18 (noble gases)8(except for helium with 2)

Answer 6

In a neutral atom, the number of electrons equals the atomic number. This is because the atomic number is the number of protons in the atomic nucleus, and in a neutral atom, the number of protons equals the number of electrons.

Answer 7

For neutral atoms the atomic number is equal to the number of electrons.

Answer 8

they are the same. the elements have the same number of electrons and protons wethere it be 1 each or 70 of each

Answer 9

Sodium (Na) lose 1

Beryllium (Be) lose 2

Boron (B) lose 3

Nitrogen (N) gain 3

Sulfur (S) gain 2

Fluorine (F) gain 1

Answer 10

Noble gases are always stable, so they generally do not lose or gain electrons. This is because they do not need to gain or lose any to acheive a full valence shell.
