How many electrons are in the outer energy level of the atoms of alkali earth metals?

There are two electrons on the outer shell which means they are pretty reactive. (make bonding easier)

Is it true that a covalent bond is formed between atoms when they share electrons to complete their valence energy levels?
Atoms covalently bond to share electrons most done between metals and non metals
What is the ability of an atom to borrow or lend electrons?
Nonmetal atoms are the atoms that borrow electrons. The number of atoms that can be borrowed or lent are what's known as valence.
Which group of metals is charterised by a single valence electron and very active atoms?
Those are the alkali metals.
How does a metallic bong differ from an ionic bond?
In an ionic bond, electrons are transferred from atoms of a metal to atoms of a non-metal, because metals lose electrons to form positive ions (cations) and non-metals gain electrons to form negative ions (anions.)In metallic bonding, electrons of one atom are interchangable with electrons of another atom. This means there's a "sea" of electricity at all times between the atoms of metals, which explains why metals conduct energy well, and other physical properties such as malleability and ductility.
Which types of atoms pool their valence electrons to form a sea of electrons?
Metals
What group of metals is characterized by a single valence electrons and very reactive atoms?
The alkali metals easily yield the one electron found in their valence shell, to bond with other elements. Since it takes so little energy to remove this electron from an alkali metal (i.e., they have a low ionization energy) these metals are never found in nature in their elemental forms (they are too reactive; i.e., their atoms so easily bond to other atoms).
What types of atoms form positive ions?
atoms that belong to a metal element....because metals always loose electrons and gain a positive charge..!
What is it called when free electrons in metals transferring energy by colliding with other atoms or electrons?
conduction
Why are alkali metals more reactive than transitional metals?
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
What is a substance that has lost or gained electrons?
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.

What does heat travel with easily through metals?
Metals are good heat conductors. The electrons are also exicted by thermal energy and that thermal energy rapidly moves to other atoms.

What is the difference from a ionic bond and a covalent bond?
A covalent bond is formed when two or more non-metallic atoms share a pair of valence electrons.Non-metal atoms will want to share electrons in order to obtain a full valence energy level.Ionic bonds results when electrons are transferred from metal atoms to non-metal atomsRecall that metals are on the left side of the periodic table (alkali metals and alkaline earth metals) and non-metals are on the right side (oxygen's family and the halogens, for example)The metal atoms will lose valence electrons to become positive ions (cations) while the non-metal atoms will gain electrons to form negative ions (anions).
Why alkali metals are more reactive than alkaline earth metals?
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.
Why are the alkali metals and the hologens very reactive?
Alkali metals have only 1 electron in their outermost (ultimate) shell. This means the atom needs energy to loose only one electron to have a completely filled outermost shell. Other atoms with 2 or 3 electrons would have needed more than twice or thrice the energy than these to loose electrons. Hence alkali metals are highly reactive compared to others. Like alkali metals, who need to LOOSE 1 electron to have a completely filled outermost shell, halogens need to GAIN 1 electron to have a completely filled outermost shell. With the same theory mentioned above, they are highly reactive.
