Oct 7, 2024 · A sodium atom consists of 11 protons, 12 neutrons, and 11 electrons arranged in three shells: 2 in the first shell, 8 in the second, and 1 in the third. The nucleus contains the protons and neutrons, while the presence of the outer electron makes sodium highly reactive. When losing its outer electron, sodium forms a positively charged ion (Na+).

Nov 7, 2024 · An atom is made up of three primary particles: protons, neutrons, and electrons. Protons are positively charged, electrons are negatively charged, and neutrons have no charge. Atomic Number: The atomic number of an element is equal to the number of protons in its nucleus. For sodium (Na), the atomic number is 11. Neutral Atoms:

Sep 14, 2023 · When it forms an ion, it loses an electron resulting in a positive ion (Na+) with 10 electrons, 11 protons, and 12 neutrons. The valency of sodium is 1. Explanation: The atom being referred to is sodium. The atomic number, which is the number of protons, for sodium is 11. The mass number provided is 23, which is the sum of protons and neutrons ...

Sep 30, 2020 · This means sodium has 11 protons in its nucleus. The number of protons defines the element itself. Number of Electrons: For a neutral atom, the number of electrons is equal to the number of protons. Since sodium has 11 protons, it also has 11 electrons. Number of Neutrons: The atomic mass of sodium is approximately 22.99, which we can round to ...

Oct 20, 2023 · The correct option for Sodium-12 (Na-12) and Sodium-20 (Na-20) is 'a': Na-12 has 11 protons, 1 neutron, and 11 electrons; and Na-20 has 11 protons, 9 neutrons, and 11 electrons. This is because the atomic number, which represent the number of protons and electrons in a neutral atom, for sodium is 11.

A sodium-23 (Na-23) atom has 11 protons, 12 neutrons, and 10 electrons. The +1 charge indicates that it has lost one electron compared to a neutral sodium atom. The number of protons helps determine the elements and is equal to the atomic number, while the number of neutrons is found by subtracting the atomic number from the atomic mass.

Apr 30, 2018 · To determine the number of protons, electrons, and neutrons in a sodium (Na) atom, we can reference its atomic structure. Sodium has an atomic number of 11, which tells us the number of protons in the nucleus. Therefore, sodium has: Number of protons = 11 . Since sodium is a neutral atom, it has the same number of electrons as protons.

Dec 18, 2024 · A sodium ion, typically denoted as Na+, has 11 protons and 10 electrons. The number of protons in an atom or ion is equal to its atomic number, which is 11 for sodium.

Oct 28, 2024 · An atom with 11 electrons (and, presumably, 11 protons) has the atomic number of 11: sodium (Na). With 11 protons and 12 neutrons, its molecular weight is 23 -- the most common atomic mass of Na.

Just remember the atomic number is the amount of protons and electrons there is 11 in sodium, and 12 neutrons in sodium. To find neutrons you round the Atomic Mass if needed then subtract it from ...
