Do alkali metals contain 7 valence electrons?
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
What are metals that have 2 valence electrons?
alkaline earth metals (group 2 elements) have two valence electrons
How many valence electrons are in alkali metals?
one valence electrons
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
When metals react with other elements what happen to the valence electrons of the metals atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
How many valence electrons are in iridium?
2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the alkaline-earth metals which contains 2 valence electrons in that group making the transition metals have 2 valence electrons.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Explain why metals react with non-metals.?
The simplest explanation is that metals have valence electrons to give away, and non metals need extra electrons to complete their valence shell.
When metals react with other elements what happens to the valence electrons of the the atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
Why metals are good conducter of electricity?
Metals have more free electrons/valence electrons/
How many valence electrons are in alkaline earth metals?
Alkaline earths have 2 valence electrons.
When metals react to the other elements what happens to the valence electrons of the metal Atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
