Sodium Hydroxide is an alkali. Alkaline is an adjective used to describe things that are alkalies. All alkalies are alkaline be definition.
Almost everything. Your stomach has the same acid that is found in a car battery. Alkaline batteries have an alkaline substance in them. Milk is a weak alkaline. Vinegar (which is the base of pickle juice) is an alkaline substance. Vitamin C is an acid. There list is truly endless.
the yellow elements in the periodic table of elements indicate that these things are made by humans
A corrosive material is something that corrodes- eats away- other things. That can include flesh or metal. Corrosives can be strongly alkaline or strongly acidic.
they are used for metal-like things,
Alkaline earth metals are group 2 elements and have 2 valence electrons.

When alkali metals react with water they produce an alkali (basic) solution. No because they form basic oxides and they neutralise acids
The metals in the living things usually are combined with other elements in chemical compounds.

So many different things depending on the context of the science. In Biology: Which kingdom an animal belongs to in order to qualitative its biological characteristics and/or behavior. For example: Mammals, amphibians, vertebrates, invertebrates, anthropods. In Chemistry: To classify chemicals with similar characteristics, such as in the periodic table. Group I Alkalis, Group II, Alkaline Earth Metals, Transition Metals, VII Halogens, VIII Inert gases. In Physics: Families of particles: leptons (electrons, quarks), mesons (pi), bosons. So briefly, 'class' is putting a wide sample of something into smaller categories which share similar characteristics.
