there are 3 energy levels in a sodium atom. in the first one there are 2 electrons, in the second one there are 8 electrons and in the third one there is 1 electron.
The magnesium atom is electrically neutral. It has 12 protons in the nucleus, which are positively charged, and 12 electrons surrounding the nucleus, which are negatively charged. The positive and negative charges balance each other out, resulting in an overall neutral charge for the atom.
When an atom's electrical charges are balanced, the atom is electrically neutral. This means it has an equal number of protons (positively charged) and electrons (negatively charged).
A neutral sodium atom has 11 electrons. This corresponds to the atomic number of sodium, which is 11.
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
the element sodium has 1,000,000 million energy levels.
A sodium ion differs from a sodium atom in that the sodium ion has a missing electron electron. It has a positive charge, as opposed to the atom, which is neutral.
All atoms are electrically neutral. If an atom gains or loses an electron, we call it an "ion" rather than an atom.
An example of an electrically neutral atom is carbon. Carbon has 6 protons and 6 electrons, giving it an equal number of positive and negative charges, which cancels out to make it electrically neutral.
The magnesium atom is electrically neutral. It has 12 protons in the nucleus, which are positively charged, and 12 electrons surrounding the nucleus, which are negatively charged. The positive and negative charges balance each other out, resulting in an overall neutral charge for the atom.
An alumimium atom is electrically neutral and it is an isotope of aluminum.
You cannot know for sure withoutmore information. An electrically neutral sodium atom (sodium has at. no. 11) will have the same number of electrons as protons; atomic number tells you the number of protons, so this atom has 11 protons and would have 11 electrons if electrically neutral, however, if the atom is charged, it could have more or fewer electrons. Sodium atoms in stars are highly ionized and may have just a few if any any electrons.

An atom is electrically neutral because it has the same number of protons (positively charged) in its nucleus as electrons (negatively charged) surrounding the nucleus. This balancing of positive and negative charges within the atom results in an overall neutral charge.
When an atom's electrical charges are balanced, the atom is electrically neutral. This means it has an equal number of protons (positively charged) and electrons (negatively charged).
Generally an atom contains similar number of electrons and protons. That is why an atom is neutral.
