A specific element cannot be mentioned as it tends to bond ionically with other compounds. Most compounds of the alkali metals are ionic. However, it can be said that a reactive metal element and a non metal element can form ionic bonds in most cases.
Bromine is a non-metal so it can form covalent or ionic bonds
Most metals and some non metals.
it has 1 atomic number
Rb
covalent bond
Group 1A is the alkali metals and since they are of small electronegativity they bond ionically, usually to nonmetals.
BaCl2 is ionically bonded.
The sodium and hydroxide are ionically bonded: Na+ OH-
Rb
Depends on the compound; chlorine can form an ionic bond with many elements. eg, NaCl, MgCl2, CsCl.
K and Br bond ionically.
covalent bond
Group 1A is the alkali metals and since they are of small electronegativity they bond ionically, usually to nonmetals.
BaCl2 is ionically bonded.
NaCl is ionic, but it is not a molecule. Molecules can only be covalent.
The compound KF is ionically bonded.
it will ionically bond to form xx
The sodium and hydroxide are ionically bonded: Na+ OH-
Copper (II) sulfate is ionically bonded.
so they cant disolve
