Question

ELEMENT ATOMIC NUMBER ELECTRONIC CONFIGURATION

NEON

CALCIUM

PHOSPHORUS

FLOURINE

ALUMINIUM​

Answer 1

Explanation:

Neon

Electron configuration [He] 2s2 2p6

Electrons per shell 2,

A calcium atom has twenty electrons, arranged in the electron configuration [Ar]4s2.

the Phosphorus electron configuration will be 1s22s22p63s23p3. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom

Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Its atomic number is 9 and its atomic weight is 19, and it's a gas at room temperature Symbol F

Electron Configuration 1s22s22p5

The electron configuration for Aluminum is 1s22s22p63s23p1. The ground state electron configuration is [Ne]3s23p1.
