How many valence electrons does alkaline earth metal have?
2
Why do alkaline metals and alkaline-earth metals reactso violently?
Alkali metals and alkaline-earth metals react violently with water or air because they have low ionization energies, meaning they readily lose electrons to form positive ions. When they react, they release a large amount of energy as heat and produce hydrogen gas. This rapid release of energy and gas can result in explosions or violent reactions.
Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What are the key differences between alkaline earth metals and alkali metals?
Alkaline earth metals have two valence electrons, while alkali metals have one valence electron. Alkaline earth metals are harder and have higher melting points compared to alkali metals. Additionally, alkaline earth metals are less reactive than alkali metals.
What element has 2 valence electrons and 4 energy levels?
Well, honey, that element you're looking for is calcium. It's got 2 valence electrons and 4 energy levels, making it quite the popular choice for chemical bonding. So, there you have it, calcium is your guy in this electron game.
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
What is the name for metals with two electrons in the outer energy level?
They are called Alkaline Earth Metals
Which are products of the alkaline and earth alkaline metals combustion?
Alkaline metals and alkaline earth metals form their oxides when burnt. These oxides are base.
Which is more metallic alkaline metals or alkaline earth metals?
alkali metals
Do alkali metals react slower or faster than alkaline earth metals?
Alkali metals react faster than alkaline earth metals due to their lower ionization energy and higher reactivity. Alkali metals readily lose their outermost electron to form a +1 cation, making them highly reactive with water and air. Alkaline earth metals, on the other hand, are less reactive as they have higher ionization energies and require more energy to lose their outer electron.
What elements has 2 main energy levels and seven valence electrons?
Alkaline earth elements have two valence electrons Those are the alkaline earth metals, technically referred to as Group 2. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra). Radium has two valence electrons and is in Group 2, but is sometimes left off lists of the alkaline earth metals because it is radioactive. - Soccer_Fanatic18
