Radium (Ra). Larger the atomic particles, less energy is used to ionize. You can also think of this in terms that Fluorine (F) is on the opposite side of the Periodic Table, which is the highest of the elements in terms of ionization energy.

∙ 13y agoNoble metals are least reactive metals as they do not react with water , air , acids , bases and other substance.
For example :gold and platinum are the least reactive metals and are also called noble metals

^It's not Ra, it's Na, aka Sodium

∙ 14y agoThis could be a trick answer, because hydrogen is theorized to be a metal at the right temperature and pressure. However, most likely the answer you are looking for is lithium

Examples of ionic and covalent compounds?
Ionic compounds: NaCl, KOH, CuSO4, etc. Any compound containing a metal and a non-metal. In ionic compounds, metals have positive ions (they lose electrons to the non metal) and non-metals have negative ions (as they gain electrons from the metal) Covalent compounds: CH4, BF3, NH3, all hydrocarbons/ all compounds containing only non-metals.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.
What element is most likely to lose electrons to become a cation?
Ions formed due to gain or lose of electrons from an Atom. Ion is an atom which does not have a full valence band. The ions with least number of electrons on the outer most shell has a high risk of losing it's valence electron.
All metals are conductors?
by defining all metals would be wrong as synthetic metals would change the properties of the metal. in terms of natural metals or alloys, yes they are all conductors as their arrangements allow them to have delocalised electrons to carry electricity
Are most elements metals or pure?
Any metal that is not an alloy of a metal with other elements (metals, metalloids, or nonmetals) is a pure element. All of the metals listed on the Periodic Table are pure elements.

Do metals donate or accept electrons and what do they become?
Metals donate electrons by losing electrons and forming positive ions.
Is niobium metal nonmetal or metalloid?
Niobium (symbol Nb) is a metal. It belongs to d-block elements or transition metals.
Which part of metallic bonding theory helps the most to explain why metals are able to conduct electricity?
Electrons can move freely among all the atoms of the metal.
What element is a metal with 2 valence electron?
All alkali earth metals have 2 valence electrons.

How do the electron dot diagrams of metal ions differ from those of nonmetal ions?
non metals generally have more valence electrons and non metal have less

What group name of metals is the most reactive?
all the metals are reactive but the most reative metal is iron.
Does calcium want to keep all of its electrons?
Calcium is a metal. Metals give away their electrons off to non-metals. So i would say when calcium is combining with another atom it wants to give away its electrons so it can be an ion.
Are most elements metals or pure?
Any metal that is not an alloy of a metal with other elements (metals, metalloids, or nonmetals) is a pure element. All of the metals listed on the Periodic Table are pure elements.
What type of bonding take place in metals?
In metals there is metallic bonding, in which all the metal atoms contribute valence electrons to a commonly shared electron cloud.
