Circle the letter of each sentence that is true about alkaline earth metals?
a. each is a good conductor of electricity b. they are never found uncombined in nature c. they lose two electrons in chemical reactions
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
What is the charge of any ion formed by an alkaline earth metal?
Alkaline earth metals are in the 2nd column of the periodic table. They can lose up to 2 electrons without having to pull electrons out of an inner shell, and so alkaline earth metals almost always have a charge of +2
What is one fact about alkaline earth metals?
they have two valence electrons
What element is an example of an alkaline earth metal?
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
What prefers to receive electrons in chemical reactions?
The outermost, known as the valance electrons.
How many electrons does a nonmetal and metal receive during a chemical reaction?
In general chemical reactions, metals tend to loose electrons and non-metals gain electrons. The no. of electrons loosed by metals is the same as the no. of electrons gained by the non-metals.
Do metals prefer to receive electrons in chemical reactions?
Yes. Metals lose their valence electrons to form cations, or positive ions. Once they lose electrons, the number of protons in their nuclei outnumber the electrons, hence the positive charge.
Do alkali metals tend to gain or lose electrons?
Alkali metals tend to lose electrons in chemical reactions.
Nonmetals during a chemical combinations tend to do what?
Non-metals during a chemical combinations tend to gain electrons. Metals in chemical reactions will tend to lose their electrons easily.
Do non-metals gain electrons in chemical reactions?
during a chemical reaction valence electrons are most always transferred
Explain how the properties of outer shell electrons affect metals?
Thrse electrons are involved in chemical reactions.
How are metals and non metals recognized?
Metals have certain features which make them easy to recognize. They have a metallic luster, and they are very good conductors of electricity. They undergo chemical reactions in which they lose electrons. Non metals characteristically do not have a metallic luster, do not conduct electricity very well, and they undergo chemical reactions in which they gain electrons (or in the case of inert gases, they don't undergo any chemical reactions).
Circle the letter of each sentence that is true about alkaline earth metals?
a. each is a good conductor of electricity b. they are never found uncombined in nature c. they lose two electrons in chemical reactions
Would you expect calcium to gain or lose electrons in a chemical reactions?
Like all metals calcium will lose electrons.
How many electrons are in the alkaline earth metals family?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
Do nonmetals loses electrons?
No. Nonmetals generally gain electrons during chemical reactions.
