what element has 10 electrons

What is its charge? Solution: Using the periodic table, we see that oxygen has an atomic number of 8, meaning that a neutral oxygen atom would have 8 protons and 8 neutrons. The oxide ion has 10 electrons, so it has gained two electrons, and has a charge of 2− .

What element has 8 neutrons 7 protons and 10 electrons?

A nitride ion has 7 protons, 8 neutrons, and 10 electrons.

Which chemical species contains 13 protons 14 neutrons and 10 electrons?

Explanation: may be the answer is aluminium.

Why does sodium have 11 electrons?

The atomic number of an element tells you how many protons that the element has. This is written at the bottom left hand side of the symbol. Since atoms are neutral, we know then that sodium atoms must also have 11 negative electrons to cancel the charge from 11 positive protons.

How many ions are in Na+?

Each molecule of Sodium chroride holds two atomic ions bonded in an ionic bond- Na+ and Cl− in a 1:1 ratio. This means that the amount of molecules correspond with each of the individual ions. So the total amount of ions is twice this number, 2.990×1023 ions in total.

What is Na+ electron configuration?

[Ne] 3s¹

What is electron explain?

An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.

What does Z mean in Chem?

Z = atomic number = number of protons in the nucleus = number of electrons orbiting the nucleus; A = mass number = number of protons and neutrons in the most common (or most stable) nucleus.
