Would you expect calcium to gain or lose electrons in a chemical reactions?
Like all metals calcium will lose electrons.
What electric forces between oppositely charged electrons and protons have to do with chemical reactions?
When metals react, they lose electrons to become stable and sometimes form a compound
Why is silicon a poor electrical conductor and copper a good conductor?
It is due to the availablity of "free electrons". All metals such as Copper can be considered as atomic nuclei surrounded by a "sea" of electrons which are free to move around with little resistance, which makes all metals good conductors of electricity (and heat, incidentally). In Silicon, a semiconductor, the electrons are mostly locked up into the silicon crystal lattice structure and free electrons are rare, occurring only when thermal effects release them temporarily from the lattice (leaving behind what is called a "hole"). These free electrons and holes occurring due to thermal effects are called "intrinsic carriers" and the hotter the silicon gets, the more of these intrinsic carriers there will be around. Thus with silicon and other semiconductors, electric current flows more easily (less resistance) as the material gets hotter, while the reverse is true for metals.
Atoms of metals do what with electrons to become stable while atoms nonmetals tend to do what to electrons to become stable?
Choices: a) eject, retain B) lose, gain c) retain,gain d) gain, lose e) lose, retain
Is silicon a metal or a nonmetal?
It is a metalloid, it has both metallic and non-metallic properties.
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 alkaline earth metals lose 2 electrons in chemical reactions?
Yes
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).
Would you expect calcium to gain or lose electrons in a chemical reactions?
Like all metals calcium will lose electrons.
Do nonmetals loses electrons?
No. Nonmetals generally gain electrons during chemical reactions.
What will the alkali metals family do with its valence electrons during a compound formation?
Alkali metals lose one electron in chemical reactions.
