Which element has 3 electrons in outer shell?
Lithium
Lithium (At. No. = 3) has three electrons, two in the K shell and one located farther from the nucleus in the L shell.
What element has 6 electrons orbits?
CARBON
So… for the element of CARBON, you already know that the atomic number tells you the number of electrons. That means there are 6 electrons in a carbon atom. Looking at the picture, you can see there are two electrons in shell one and four electrons in shell two. ► More about the history and places to find carbon.
What element has 3 orbitals and 3 valence electrons?
Scandium atomic number 21 is in the fourth period. s, p and d . 1st , 2st , 3rd and 4th . for a total of 3 valance electrons.
Which element has 3 electrons in the valence shell?
Lithium has 3 electrons — 2 in the first shell, and 1 in the second shell (so one valence electron).
What element has 6 valence electrons and 3 energy levels?
Why is the Periodic Table Arranged the Way it Is? OXYGEN FAMILY: All have 6 VALENCE ELECTRONS (electrons in the outer energy level) Oxygen, sulfur, and selenium are NONMETALS.
How many electrons does element 6 have?
6 electrons
It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
How many electrons are in 6th shell?
72

How many valence electrons do B have?
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 makes a particular element very reactive and another element non-reactive?
| Element Name | Boron |
|---|---|
| Symbol | B |
| Atomic Number | 5 |
| Electron Configuration | 1s22s22p1 |
What elements has 3 energy levels?
Sodium is in the third period, so it has three energy levels. As the number describing the energy level increases, the energy of that level also increases. Next, each energy level has sublevels, or subshells, which contain different atomic orbitals.
What element has 3 shells and 2 valence electrons?
List of elements with electrons per shell
| Z | Element | No. of electrons/shell |
|---|---|---|
| 2 | Helium | 2 |
| 3 | Lithium | 2, 1 |
| 4 | Beryllium | 2, 2 |
| 5 | Boron | 2, 3 |
Which element has total three shells and three electrons in its valence shell single choice?
the element is silicon. d-first shell is completely filled and valence shell has three electrons so its electronic configuration will be 2,3. therefore the element is Boron.
How many electrons are in the outermost orbit of an atom?
Element A has 3 electrons in the outermost orbit and element B has 6 electrons in the outermost orbit. The formula of the compound formed A and B would be: Element A has 3 electrons in the outermost orbit and element B has 6 electrons in the outermost orbit.
How many electrons does A and B have in their octet?
A has 3 electrons in outermost orbit and B has 6 electrons in its outermost orbits. So A can give three electrons to complete its octet and B need 2 electrons to complete its octet. so 2 atoms of A will release 6 electrons and 3 atoms of B will need six electrons to complete their octet .
What is the electron configuration of a2b3?
A has 3 electrons in outermost orbit and B has 6 electrons in its outermost orbits. So A can give three electrons to complete its octet and B need 2 electrons to complete its octet. so 2 atoms of A will release 6 electrons and 3 atoms of B will need six electrons to complete their octet So, the formula will be A2 B3
What is the product of valence electrons in a neutral molecule?
In a neutral (uncharged) molecule, the sum of the bonding valence electrons must be equal. So, the products of the negative element and its charge and the positive element and its charge must be equal.
