is carbon dioxide is alkali metalwhich is not alkali metal
Answers
Answer:
The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K),[note 1] rubidium (Rb), caesium (Cs),[note 2] and francium (Fr). Together with hydrogen they constitute group 1,[note 3] which lies in the s-block of the periodic table. All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.[note 4] Indeed, the alkali metals provide the best example of group trends in properties in the periodic table, with elements exhibiting well-characterised homologous behaviour. This family of elements is also known as the lithium family after its leading element.
Answer:
Explanation:
Alkali metals are the elements in group 1 of the periodic table. Alkaline earth metals are the elements in group 2 of the periodic table. Both show basic properties. ... The main difference between alkaline and alkali is that alkali metals have one valence electron, whereas alkaline earth metals have two valence electrons.
A weak alkali has a pH of 11 or 12. but most of them stay as molecules. (NH4OH(aq)). This is also called ammonia solution
pH 0 – 2: strong acid.
pH 3 – 6: weak acid.
pH 7: neutral.
pH 8 – 11: weak alkali.
pH 12 – 14: strong alkali.
