How many protons electrons and neutrons are in sodium chloride?

How many protons electrons and neutrons are in sodium chloride?

Protons = 17, electrons = 18, neutrons = 18. Hint: Sodium chloride (NaCl) is the combination of sodium ion Na+ and chloride ion Cl− and commonly known as common salt or table salt.

How many electrons are in the element neon?

Neon/Electrons per shell

How many electrons does NaCl have?

Sodium chloride (NaCl) is a typical ionic compound. The picture below shows both a sodium and a chlorine ion. Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons.

How many neutrons are in neon?

ten neutrons
Neon is an atom with atomic number ten. Its atomic weight is 20.179 which cause it to have ten neutrons and ten protons in its nucleus and ten electrons outside.

Why does sodium have 12 neutrons?

The number of 23 amu means that a normal, or stable, sodium atom weighs 23 unified atomic mass units. Since sodium atoms have 11 protons, this means that a normal sodium atom has 23 – 11 = 12 neutrons.

Why does sodium lose an electron?

As Figure 1 illustrates, sodium (Na) only has one electron in its outer electron shell. It takes less energy for sodium to donate that one electron than it does to accept seven more electrons to fill the outer shell. Again, it is more energy-efficient for chlorine to gain one electron than to lose seven.

What is the smallest atom in the world?

hydrogen atom
The smallest atom? If by “biggest” and “smallest”, you mean mass (which is a measure of how much matter is there), then the smallest is the hydrogen atom with one proton and one electron.

How many electrons are in an oxygen atom?

2, 6
Oxygen/Electrons per shell

Is NaCl a proton?

Sodium chloride is an example of an ionic solid. A sodium atom, which has 11 protons and 11 electrons, has a single valence electron in its 3s subshell.

Which is more stable CL or CL?

Re: Stability of Cl vs Cl- After Cl gains another electron, it has an octet. This means Cl- is more stable and less reactive because it now has a full set of valence electrons. Cl- will no longer look for more electrons.

What has 9 protons and 9 neutrons?

By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it’s mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

How many protons does sodium 12 have?

11 protons
So sodium has 11 protons and 11 electrons. The mass number is 23. The number of neutrons = mass number – atomic number. The number of neutrons = 23 – 11 = 12.
