Question

A neutral atom has the following electron configuration: 152s 2p 3s What is the chemical symbol for the atom? How many electr

science chemistry

Answer 1

Answer #1

•Neutral atom=> Number of electron = number of proton

Electronic configuration:-

1s2 2s2 2p6 3s2

Total number of electron = 12

Number of proton = 12

Atomic number = 12

Element = Magnesium

[]

Chemical symbol of atom = Mg

Number of electrons in an atom = 12

Number of 3d electrons = 0

Answer 2

The electron configuration can also be represented by writing the symbol for the occupied subshell and adding a superscript to indicate the number of electrons in that subshell. For example, consider a carbon atom having an atomic number of 6. The total number of electrons in a neutral carbon atom is 6. The electron configuration of the carbon atom represented by the orbital diagram is Electron 1s, 2s, and 2p each contain two single harpoon up arrows. This electron configuration...
