What element has 2 valence electrons and 6 energy level?
What element has 2 valence electrons and 6 energy level?
A: Calcium is a group 2 element with two valence electrons. Therefore, it is very reactive and gives up electrons in chemical reactions. It is likely to react with an element with six valence electrons that “wants” to gain two electrons. This would be an element in group 6, such as oxygen.
Which elements has 2 valence electrons?
Group -2 elements have 2 valence electrons in their valence shell. These group elements are commonly called as Alkaline Earth metals. Some examples are Berrylium,Calcium,Strontium,Barium,Magnesium etc.
What elements have a valence of 6?
They are oxygen (O) , sulfur (S) , selenium (Se) , tellurium (Te) , and polonium (Po) . Note that the synthetic element livermorium (element number 116 ) is also predicted to have six valence electrons, but it’s not proven yet. These elements all belong in group 16 or the chalcogens group.
How many electrons are in the 6th energy level?
Questions and Answers
| Energy Level (Principal Quantum Number) | Shell Letter | Electron Capacity |
|---|---|---|
| 3 | M | 18 |
| 4 | N | 32 |
| 5 | O | 50 |
| 6 | P | 72 |
What element has 2 valence electrons and 2 energy levels?
Lithium has a single electron in the second principal energy level and so we say that lithium has one valence electron. Beryllium has two valence electrons.
What element has 6 protons and 6 neutrons and 6 electrons?
carbon
Before you start, take a look at carbon on the periodic table. It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
Which element has 2 energy levels shells )?
Helium
Electrons
| Atomic Number | Element | Energy Levels or “shells” |
|---|---|---|
| 2 | Helium (He) | 2 |
| 3 | Lithium (Li) | 2 |
| 4 | Beryllium (Be) | 2 |
| 5 | Boron (B) | 2 |
How many Subshells are in the 6th shell?
This model breaks down at the n=3 shell because each shell has subshells. There are 4 subshells, s, p, d, and f….Search form.
| Shell | Subshell | Total Number of Electrons in Shell |
|---|---|---|
| 4th Shell | 4s, 4p, 4d, 4f | 2 + 6 + 10 + 14 = 32 |
How many orbitals are in the 6th shell?
The quantum number n represents the shell number, and n = 6 represents the 6th shell (and sixth period on the periodic table). The quantum number l represents the subshell number, and l = 3 represents f-orbitals, so there will be 7 orbitals in a 6f subshell.
Which elements have valence electrons in the second energy level?
Elements in the second row (lithium through neon) will have valence electrons in the second energy level with a principal quantum number of 2. The trend continues all the way down to the seventh row.
How many valence electrons do the elements in the carbon family have?
The elements in the carbon family all will have four valence electrons, the elements in the nitrogen family will have five, the elements in the oxygen family will have six, the halogens will have seven valence electrons and aside from helium,…
Where are valence electrons found in the periodic table?
But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core. If you want a Periodic table with Valence electrons, then visit Periodic table with Valence electrons labeled in it.
What is the principal quantum number of a valence electron?
For example, that one valence electron in lithium is in the 2 s orbital. That number 2 is the principal quantum number that represents the size of the orbital. The 2 s orbital is going to be a lot smaller than the 4 s orbital in potassium that holds its valence electron.
