## How Many Electrons Does Sodium Have

### How many electrons go into the first sodium layer?

For the element SODIUM, you already know that the atomic number indicates the number of electrons. This means that one sodium atom contains 11 electrons. If you look at the picture you can see that there are two electrons in layer one, eight in layer two and one in layer three.

### 11 electronsHow many electrons does sodium number 11 have to lose to become saturated?

When sodium (group 1) loses 1 electron, it acquires a complete outer shell. Since the sodium ion therefore has 11 protons but only 10 electrons, it occupies the +1 position. Calcium, the next atom, must lose 2 electrons to get a complete outer shell, which gives it a +2 charge.

### Likewise, how many electrons are there in a shell?

Each shell can only hold a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10 . ), etc. As a general formula, the ninth shell can in principle contain a maximum of 2 (n2) electrons.

### How many orbitals does sodium have?

When writing the configuration, place the 11 electrons in the orbitals around the nucleus of the sodium atom.

### Why are there only two electrons in the first shell?

This first layer has only one substrate (marked 1s) and can hold up to 2 electrons. So there are two elements in the first row of the periodic table (H & He). Since the first shell can hold a maximum of 2 electrons, the third electron must enter the second shell.

### How is the value calculated?

The valence of an atom corresponds to the number of electrons in its outer shell, whether the number is four or less. Otherwise the valence is eight minus the number of electrons in the outer shell. Once you know the number of electrons you can easily calculate the valence.

### What is a subshell?

A substrate is a division of electron layers separated by electron orbitals. The substrates are labeled s, p, d and f in an electron configuration.

### How many electrons does the fourth layer have?

The fourth energy level has 18 electrons. The fourth energy level of the periodic table consists of the 4s 3d and 4p orbitals. The 4p orbital has 6 electrons.

### How many electrons does Na + contain?

A Na + ion is a sodium atom that has lost an electron because it makes the number of electrons in the atom equal to that of the closest 10-electron noble gas neon. This completely fills the first and second electron layers. The sodium atom has 11 protons, 11 electrons and 12 neutrons.

### How many electrons can 5f hold?

Each orbit can hold two electrons, so the capacity of a nf subshell is 14 electrons.

### How many electrons can the seventh shell have?

Note that you can easily determine the number of electrons an atom can hold on a given shell or energy level by taking advantage of the fact that each orbit can hold a maximum of two electrons.

### What do electrons in the same shell have in common?

They have the same amount of energy.
