Answer:
○Two electrons in the outer shell and a full outer electron s shell
○Low electron affinities
○Low electronegativities
○Relatively low densities
○Relatively low melting points and boiling points, as far as metals are concerned
○Typically malleable and ductile. Relatively soft and strong.
The elements readily form divalent cations (such as Mg2+and Ca2+).
The alkaline earth metals are very reactive, although less so than the alkali metals. Because of their high reactivity, the alkaline earths are not found free in nature. However, all of these elements do occur naturally. They are common in a wide variety of compounds and minerals.
These elements are shiny and silver-white as pure metals, although they usually appear dull because they react with air to form surface oxide layers.
All the alkaline earths, except for beryllium, form corrosive alkaline hydroxides.
All of the alkaline earths react with halogens to form halides. The halides are ionic crystals, except for beryllium chloride, which is a covalent compound.
Answer:
weight
Explanation:
The gravitational force between a mass and the Earth is the object's weight.
Interphase is when the cell grows and duplicates chromosomes. This is important for the cell to divide, because otherwise, the cell would shrink everytime it divided and would not have a sufficient amount of DNA
Answer:
Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place
Explanation:
Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity.
Answer:
the sun's rays hit the Earth at a shallow angle because the sun is lower in the sky.The long nights and short days prevent the Earth from warming up.
