What is the electron of Li?
3 electrons
So… for the element of LITHIUM, you already know that the atomic number tells you the number of electrons. That means there are 3 electrons in a lithium atom.
What is the electron configuration for Li which has 3 electrons?
1s22s1
The atomic number of lithium (Li) is 3. Therefore its atoms contain 3 protons. A neutral atom has equal numbers of protons and electrons, so a neutral Li atom also has 3 electrons. The electron configuration of Li is 1s22s1 .
How many shells are used to write the electron configuration of Li?
6.1 Shell diagram of lithium (Li) atom. The next largest atom, beryllium, has 4 electrons, so its electron configuration is 1s22s2….2.6: Arrangements of Electrons.
| Shell | Number of Subshells | Names of Subshells |
|---|---|---|
| 4 | 4 | 4s, 4p, 4d and 4f |

Which Orbital will lose an electron when Li+ is formed?
2s-orbital
Now, the lithium cation, Li+ , is formed when lithium loses the electron located on its outermost shell → its valence electron. This electron is located on the second energy level, in the 2s-orbital.
How to calculate electron configuration?
Method 3 of 4: Using an ADOMAH Periodic Table Understand the ADOMAH Periodic Table. This method of writing electron configurations doesn’t require memorization. Find your atom in the ADOMAH table. To write electron configuration of an element, locate its symbol in ADOMAH Periodic Table and cross out all elements that have higher Count orbital sets up to your atom.
What is electron configuration used for?
The electron configuration is used to describe the orbitals of an atom in its ground state, but it can also be used to represent an atom that has ionized into a cation or anion by compensating with the loss of or gain of electrons in their subsequent orbitals.
What is the meaning of electron configuration?
Electron Configuration. Definition – What does Electron Configuration mean? Electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals; for example, the electron configuration of a neon atom is 1s2 2s2 2p6.
Which element has this electron configuration?
The electron configuration of an element describes how electrons are distributed in its atomic orbitals . Electron configurations of atoms follow a standard notation in which all electron-containing atomic subshells (with the number of electrons they hold written in superscript) are placed in a sequence.
