why do alkali metals not show plus 2 oxidation state?
why do alkali metels not show +2 oxidation state
WHY did Mendeleev arrange the elements in periods?
he put them in groups to show acids from alkali's and gasses from metals
Are alkali metals electro-positive?
Yes they are!even though they are very soft, reactive and not as widely used as much as transition metals eg. in construction they still have other metallic properties, such as metallic bonding.Yes all alkali metals are metals.
Why hydrogen is placed above alkali metals and not above non-metals in Modern Periodic Table?
It is much more common for hydrogen to lose an electron and become H+ than it is for it to become H- (like a halogen would), as in a hydride. Because it is possible for either behavior, though, some periodic tables DO show hydrogen in group 17. Some show it in group 1. Some show both, and some show hydrogen sitting in the middle by itself. It's a tricky one.
How reactive are lanthanides and actinides metals?
Lanthanides and actinides are generally less reactive than alkali or alkaline earth metals. They tend to form stable compounds and exhibit a variety of oxidation states due to the presence of f-orbitals in their electronic configuration. Actinides may show greater reactivity due to the availability of f-orbitals for bonding.

What is the oxidation numbers of alkaline metals?
The question should be either 'alkali metals' or 'alkaline earth metals'. For alkali metals or group 1 elements, the oxidation number is +1 (note. hyddrogen can have +1 and -1). For alkaline earth metals, the oxidation number is +2 In addition all these elements will have an oxidation number of 0 in their elemental form
Do alkali metals have metallic luster?
All Alkali metals show metallic lustre ,which can be explained by the oscillation of free electrons.
Which elements have oxidation number 1?
Potassium and Lithium

Which non-metals show only one oxidation number when they form compounds?
oxygen and fluorine
When do halogens show 1 and -1 oxidation states?
When halogens bind to more electropositive elements (compared it itself), they show -1 oxidation state. When halogens bind to more electronegative elements (compared it itself), they show +1 oxidation state.
Is alkali metal more reactive than transition metal?
Yes, alkali metals are more reactive than transition metals. This is because alkali metals have low ionization energies and readily lose their outermost electron to form positive ions, whereas transition metals have higher ionization energies and show a more variable reactivity depending on the particular metal and conditions.

Why does the oxidation number of all metals on the periodic table have a positive charge?
Metals tend to lose electrons to achieve a stable octet configuration. This loss of electrons results in a positive oxidation state. The positive charge corresponds to the number of electrons that the metal has lost in order to become stable.
