What would alkali metal atoms need in order to end up with the same stable electron arrangements as the noble gas?
alkali metals need to loose one electron. alkali earth metals need to loose two
Which periodic table famiy is the most reactive?
The alkali metals are the most reactive of all groups on the periodic table. Some of the metals are lithium, potassium and sodium.
What is the most reactive metals that are found in a group?
Both the alkali metals and halogens because they only need one electron, or only need to lose 1 electron
What do alkali metals react vigorously with?
An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.
Are alkali metals softer or harder than other metals?
The softness of alkali metals has to do with metallic bonding in terms of bonding and anti bonding orbitals. In molecular orbitals, there are the s, p, d orbitals with corresponding anti-bonding orbitals. For alkali metals, the s orbital is only partially filled. This means that the bonds between each atom are weak because only a cloud of s-orbital electrons are holding them together. As we move right across the periodic table the strength of metals reach a maximum at about group 7-8. This is because at this point anti-bonding and bonding orbitals are both partially filled and this maximizes the amount of unpaired electrons that participate in the electron cloud that holds metallic bonds together. As we proceed further right (toward Au) the bonds become weaker because the bonding and anti-bonding orbitals begin to fill and pair up. This means these electrons do not participate in the electron cloud of metallic bonding. Thus a weaker bond (softer metal) is formed.

Is the alkali metal more reactive than an alkaline-earth metal?
Yes, alkali metals are more reactive than alkaline-earth metals. All atoms want to have 8 electrons in their outer shells. Alkali metals have to give one electron away, where as alkaline-earth metals need to give two away which is less energetically favorable.

In writing Lewis structure how is the need for multiple bonds generally determined?
When there are not enough valence electrons to complete octets by adding unshared pairs. Source: My Chemistry Textbook :D
Why are the alkaline-earth metals less reactive than the alkali metals?
Alkaline-earth metal have two electrons in there outer shell, so only need to lose one to form a stable electron arrangement. Alkali metals have one electron in there outer shell - so they need only lose one to form a stable electron arrangement
What are elements in Groups 1 and 2 and in Groups 13-18?
Group 1- Alkali metals Group 2- Alkali earth metals Group 3-12_Transition metals Group 17-Halogens Group 18-Noble gases

Why are the alkali metals and Halogens among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
Why alkali metals and the halogens among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
