Which element has 11 protons in the nucleus?
sodium
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).
What elements has 11 valence electrons?
Table
| Z | Name | Valence electrons |
|---|---|---|
| 10 | Neon | 8 |
| 11 | Sodium | 1 |
| 12 | Magnesium | 2 |
What will be the valency of an element having 12 protons in nucleus of its atom?
So, one atom of this element can lose 2 electrons to achieve the nearest inert gas electron arrangement of 2,8. Since one atom of the element loses 2 electrons to achieve the inert gas electron configuration, so its valency is 2. It is divalent. (The element having atomic number 12 is actually magnesium).
What element has 11 protons and 9 Neutrons?
Sodium
Sodium has an atomic number of 11.
What element has 11 protons 11 neutrons?
sodium Na
The element with 11 protons is sodium Na. The sum of the protons and neutrons is the mass number, A, and is equal to 22.
Do you have 11 protons?
Any atom that contains exactly 11 protons is an atom of sodium.
What element has 11 protons and 11 neutrons in its nucleus?
What is the element with 11 electrons?
sodium atom
The sodium atom contains 11 electrons, 11 protons, and 12 neutrons.
What is the valency of an element having atomic number 11?

Valency of First 30 Elements
| Element | Atomic Number | Valency |
|---|---|---|
| Valency of Sodium (Na) | 11 | 1 |
| Valency of Magnesium (Mg) | 12 | 2 |
| Valency of Aluminium | 13 | 3 |
| Valency of Silicon | 14 | 4 |
What is valency of an element having atomic number 12?
Element with atomic number 12 is Magnesium (Mg). Electronic configuration of magnesium is 1s2 2s2 2p6 3s2. It has 2 e- in its outermost orbit and can donate these to form a stable octet. Hence, its valency is +2.
What element has 11 protons 11 neutrons and 10 electrons?
If sodium loses an electron, it now has 11 protons, 11 neutrons, and only 10 electrons, leaving it with an overall charge of +1. It is now referred to as a sodium ion.
What is the name of an atom that has 11 protons 11 electrons and 12 neutrons?
