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:

The alkaline earth metals are present inside the earth and when they are dissolved in water they form the base or alkali solution. Group 2 elements are known as alkaline earth metals.

They shows several common things like all the members show metallic property. They have low ionization energy and high electronegative energy. The atomic radius increases as we go down the group in case of the alkaline earth metals.

Whitepunk [10]

Horticulturalist’s best option is clone the desired tulip so there will be no genetic variations.

Explanation:

Cloning is a process by which replica of organism is made without having any genetically variations. It is done carefully to avoid any variations in the office bring that may be related to physical or genetic structure.

The process of cloning should be done under the supervision of expert to avoid any error which could lead to the variation in genetic structure. It is very necessary for the amateur horticulturalist who desires to have dual apps without any genetic variation to perform cloning.

If you have just eaten, your body secretes ______ to uptake glucose; if you have not eaten all day, your body secretes ______ to
pav-90 [236]
If you have just eaten, your body will secrete insulin. Insulin is the hormone that allows glucose to enter cells. That way they will have the proper energy for their normal functions.
If you have not eaten for a while, your body is running out of glucose to feed the cells so it needs to secrete another hormone called glucagon. This hormone is the complete opposite of insulin because it breaks down glycogen, proteins and fats into glucose.
