We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass). Sodium has a mass number of 23amu.

27 protons, 33 neutrons, 27 electrons The cobalt atom has 27 protons as seen in the periodic table. There are also 27 electrons because the charge is 0. There are 33 neutrons because 60-27 = 33.

Since electrons have a negative charge, gaining electrons makes the ion negative. Losing electrons makes the ion positive. If you need to determine how many electrons are in the sodium ion Na+, start with the neutral atom. Neutral sodium has 11 electrons.

A neutral atom with atomic number 20 will have 20 electrons. The atomic number is, by definiton, the number of protons in an atom's nucleus but for a neutral atom it's also equal to the number of electrons. Each element has a different, unique number of protons that determines its identity.

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges, this means that atoms are have no overall electrical charge. For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons.

Sodium atoms and sodium ions have same number of protons. Each one has 11 protons. ... Sodium ion has 10 electrons as sodium atom loses one electron to form sodium ion. Only sodium atom react vigorously with water whereas sodium ion does not.

For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4). “atomic number.”

Therefore the sodium electron configuration will be 1s22s22p63s1. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

How many protons, neutrons, and electrons are there in an atom of uranium-238? Write the symbol for this isotope. The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.
