## How many orbitals in a sodium atom contain electrons?

When we write the configuration we’ll put all 11 electrons in orbitals around the nucleus of the Sodium atom. In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital.

## What is the electronic configuration of NA 11?

When we write the configuration we’ll put all 11 electrons in orbitals around the nucleus of the Sodium atom. We’ll put six in the 2p orbital and then put the remaining electron in the 3s. Therefore the sodium electron configuration will be 1s22s22p63s1.

## How many electrons does sodium atomic number 11 need to lose to be full?

It takes less energy for sodium to donate that one electron than it does to accept seven more electrons to fill the outer shell. If sodium loses an electron, it now has 11 protons, 11 neutrons, and only 10 electrons, leaving it with an overall charge of +1.

## What is the electron configuration of an isolated F atom?

Therefore the F electron configuration will be 1s22s22p5. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.

## What is the symbol of a cation that has 11 protons and 10 electrons?

An ion with a positive charge is called a cation (pronounced CAT-ion); a negatively charged ion is called an anion (AN-ion). For example, the sodium atom, which has 11 protons and 11 electrons, easily loses one electron. The resulting cation has 11 protons and 10 electrons, and hence has a net charge of 1+.

## Can an atom have a +6 charge?

Neutral carbon-12 (or any carbon atom) has 6 electrons with a total negative charge of 6e- orbiting a nucleus with a total positive charge of 6e+, so that the total net charge is zero. The protons and neutrons have almost the same mass, and each is about 1800 times the mass of an electron.
