Yes. Metals always lose electrons and non-metals gain electrons.
Yes, 3 or 4 times as many elements are metallic.
Note, the whole left AND bottom portions of the Periodic Table are metals.
Gain.
no
yes
Iron is the most metallic in nature among these three. Therefore, it has the most strongest metallic bonds
only non metals are acidic, covalent bonding only occurs between nonmetals, metallic bonding between metals. If it is shiny it is most likely a metal except unless it is a diamond or silicon. Also you can tell on the periodic table
It depends which diagram, most likely they are electron shells as all elements have
No. They will most likely form an ionic bond. Metallic bonds form between the atoms of a metal, such as gold or iron.
The most likely electron configuration for a sodium ion in its ground state is 1s22s22p63s1.
Compounds that contain a metallic element(cation) bonded to a nonmetallic element(anion), or any compounds containing polyatomic ions would be held together by an electrostatic attraction called an ionic bond. These are formed when the metallic element donates one or more electrons to a nonmetallic element creating an uneven distribution of electrons and protons within the elements called ions. Atoms are even distributions of electrons and protons within elements. Ions are then created to achieve a level of stability within each element's nobel gas electron configuration.
Group I elements (that is alkali metals)
Elements in the d-block usually form metallic bonds with high strength.
They have relatively full valence shells.
Elements in the 1st group have 1 valence electron. So they are likely to donate 1 electron to get more stable. potassium, rubidium and cesium are likely to donate 1 electron.
metallic
Iron is the most metallic in nature among these three. Therefore, it has the most strongest metallic bonds
Nonmetals, expecially halogens.
The group 1 elements, which are the alkali metals.
Both Li and K lose electrons to get noble gas configuration. Br gains an electron to get noble gas configuration. So K is more likely to form a compound with Br.Potassium is a metal in group 1. It usually forms ionic compounds with other non metallic elements. From these elements, it is more likely to bond with bromine. Recall that lithium is as in the same family as potassium.

High Electonegativity of non metals makes them more likely to gain electrons.
