The metallic bond is the attraction between the shared electrons and the protons in each atom’s nucleus a metal cation and a nonmetal anion a metal anion and a nonmetal cation a metal cation and the shared electrons that surround it

a metal cation and the shared electrons that surround it

Explanation:

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals.In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions.

These de-localized electrons are the valence electrons of metal atoms which are shared between them.

A metal cation and a nonmetal anion are bonded by ionic bonding.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
