Is calcium a transition or representative element?
Calcium is not a transition metal. It is an Alkaline Earth metal. Not to be confused with Alkali metals, Alkaline Earth metals have two electrons in their outer shell with which they wish to transfer. Most transition metals are elements 21-30, and every row below that.
How many metals is in the earth?
There are 91 naturally occurring metals in the Earth's crust. Some of the most abundant metals include aluminum, iron, calcium, sodium, magnesium, and potassium.
What are some examples of rare earth metals?
Some examples of rare earth metals include neodymium, dysprosium, europium, and terbium. These metals are used in various high-tech applications such as electronics, magnets, and batteries due to their unique properties.
What metals are mined from earth?
Some of the metals that are mined from Earth include iron, aluminum, copper, gold, silver, and zinc. These metals are used in various industries for different purposes, such as construction, electronics, and manufacturing.
What are the scarcest metals on earth?
Some of the scarcest metals on Earth include ruthenium, rhodium, osmium, and iridium. These metals are considered rare because they are found in low concentrations in the Earth's crust and are often difficult to extract and refine.
Do metals react with water?
Some, such as the alkali metals, alkaline earth metals, and a few others do. But most don't.
Give the names of some of the families of elements in the periodic table?
They are the Alkali Metals, Alkaline Metals, Transition Metals, Metalloids, Halogens, and the Noble (Inert) Gases. There is also the lanthanide and actinide series which are known as the Rare Earth Metals.
Alkali metal and alkaline earth metal have how many ionization energies?
Alkali metals (group 1 elements) have one valence electron. Hence have one ionization energy Alkaline earth metals (group 2 elements) have two valence electron. Hence have two ionization energy
What side of a periodic table of elements has metallic properties?
the groups of alkali metals, alkaline earth metals, transition metals, and other metal are all metals and some of the metalloids have metallic properties and the alkali, alkaline are on the left, transition metals are in the middle, other metals are located directly next to the transition metals and the metalloids are next to the other metals, and then you have halogens and Nobel gases, Lanthanides and Actinides which are all gases and rare earth.
How does the hardness of the alkaline earth metals compared to the hardness of alkali metals?
Transition state metals include a wide variety of metals; they include iron, gold, and mercury which all have strikingly different properties (hard, soft, and liquid, for example). Nonetheless, a comparison can be made between the transition state metals and the alkali and alkaline earth metals; transition state metals are not as chemically active (some transition state metals are actually inert, such as platinum).
How do the properties of the transition element compare with those of the alkali metals and alkaline-earth metals?
Transition state metals include a wide variety of metals; they include iron, gold, and Mercury which all have strikingly different properties (hard, soft, and liquid, for example). Nonetheless, a comparison can be made between the transition state metals and the alkali and alkaline earth metals; transition state metals are not as chemically active (some transition state metals are actually inert, such as platinum).
Properties of alkaline earth metals?
They are extremely reactive with acid -explosively in some cases. They are also very reactive with water and form alkaline solutions and also very reactive with halogens. Apart from that they have the usual properties of metals such as ductility and lustre etc.
What elements have two valence electrons?
Some elements with two valence electrons include beryllium (Be) and magnesium (Mg) in group 2 of the periodic table. These elements have two electrons in their outermost energy level.
Is a metal an acid or alkali?
Metals are not acids or alkalis. Metals are elements that tend to lose electrons in chemical reactions, forming positive ions. Acids and alkalis are types of substances that can donate or accept protons in solution, respectively.
Why is beryllium classified as an aklaline metal?
Because beryllium has some similarities with the other alkaline earth metals; and also the electronic configuration is important.
What oxidation states can the alkaline earth metals exhibit?
0 and 2 oxidation states, and in some cases, 1 also
What are some dangers of working with alkaline eath metals?
Alkaline earth metals such as magnesium, calcium, and barium can react vigorously with water or air, producing flammable hydrogen gas. They are also toxic when ingested, and can cause skin irritation if handled without proper precautions. Additionally, alkaline earth metals can form explosive compounds if not stored or handled correctly.
