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.

<span>The cells of plants
and animals are similar expect for a few different structures like the shape of
the cells and cell wall. They differ in cell shape since animal cells are rounded
and it has irregular shape while plant cells have fixed shape which is
rectangular. Another structure is a cell wall. Animal cells don’t have cell wall
while plant cells have. Plant cell wall is a structure surrounding the cell
that provides a number of functions such as strength to support the plant, Flexibility,
Water-proofing, Barrier to pests, Protection against environmental stress, signaling
and sensing. </span>
Answer:
Chongqing, referred to as Ba and Yu, also known as Bayu, Shancheng, Yudu, and Qiaodu, is one of the four central municipalities in China, five national central cities, a national historical and cultural city, and the world's hot spring capital; the four major international metropolises positioned by the State Council, the Yangtze River It is the economic center, financial center and innovation center of the upstream region, as well as the center of politics, shipping, culture, science and technology, education, communication, etc., the national comprehensive transportation hub, and the large-scale water, land and air transportation hub in the western region. Chongqing is located in the southwest of China, in the core area of the economic belt in the upper reaches of the Yangtze River, surrounded by the Yangtze River and the Jialing River.
Explanation:
Answer:
solute
Explanation:
The cell membrane with an integral molecule that consists of two similar parts with a specific recess. There are many particles in the extracellular fluid. One of these particles is labeled A.
Structure A is a solute
Solute refers to the component which is dissolved in the solvent.
The solvent is the substance in which the solute is dissolved.
