Define nonmetal in terms of chemical reactivity?
Nonmetals are elements that tend to gain electrons in chemical reactions. They typically form negative ions (anions) by accepting electrons from other elements. Nonmetals are generally located on the right side of the periodic table.
Do metal atoms decrease in size when they combines with nonmetal atom?
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
What do metals become after the donate electrons?
Metal --> electrons + Metal ions (positively charged)
When metals and non metals react whichs atoms gain electrons?
Nonmetals usually accept electrons to become negative ions (anions), e.g. Cl + e- --> Cl-.
Rubidium has one electron in its outer level What will it most likely do in a reaction?
It will lose its outermost electron to a nonmetal. The Rb atom will become a positively charged ion with a charge of 1+ , and the nonmetal will gain the electron and become a negatively charged ion. The electrostatic attraction between the oppositely charged ions forms an ionic bond.
Which elements tend to attract electrons to become negative ions?
Nonmetals tend to attract electrons to become negative ions.
Define nonmetal in terms of chemical reactivity?
Nonmetals are elements that tend to gain electrons in chemical reactions. They typically form negative ions (anions) by accepting electrons from other elements. Nonmetals are generally located on the right side of the periodic table.
Do non-metals become positive or negative as ions?
Non-metals typically become negative ions when they form ions because they gain electrons to achieve a full outer electron shell. This results in a negative charge due to the extra electrons present in the ion.
If atoms of a halogen nonmetal gain one electron the atoms the have?
They become anions, with negative electrical charge.
What type of reaction forms when a metal and nonmetal element form an ionic compound?
When a metal and nonmetal element form an ionic compound, it is a transfer of electrons from the metal (which loses electrons to become a cation) to the nonmetal (which gains electrons to become an anion). This forms an ionic bond between the cation and anion, resulting in the formation of an ionic compound.
Why do nonmetals have a negative oxidation number?
Nonmetals tend to gain electrons to achieve a stable electron configuration and become more like noble gases. This results in a negative oxidation number because they gain electrons rather than lose them.
Do metal atoms decrease in size when they combines with nonmetal atom?
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
What are the kinds of nonmetal atoms?
Any element that is not a metal is, by definition, a nonmetal. These come in basically two types, the chemically active nonmetal and the inert nonmetal. Sulfur, oxygen, nitrogen, carbon, silicon, phosphorus, and the halogens, fluorine, chlorine, bromine, iodine, and astatine, are the most important of the chemically active nonmetals; hydrogen is an ambiguous element since it can be either a metal or a nonmetal, although it is usually a nonmetal (note that at low temperature and high pressure, hydrogen actually will become a metallic solid, with all the usual features of a metal, even though under more usual temperatures and pressures it is a transparent gas bearing no resemblance to a metal). The inert nonmetals are the noble gases, helium, neon, krypton, xenon, and radon.
Which elements would most likely become a negative ion when forming a chemical bond?
Elements on the right side of the periodic table, such as fluorine, oxygen, and chlorine, are more likely to become negative ions (anions) because they tend to gain electrons to achieve a stable electron configuration.
An ionic compound is formed when there is a reaction between what elements?
Ionic compounds are formed when a metal reacts with a nonmetal. The metal atom loses electrons to become a positively charged cation, and the nonmetal gains these electrons to become a negatively charged anion. These opposite charges attract each other, forming an ionic bond.
What do metals become after the donate electrons?
Metal --> electrons + Metal ions (positively charged)
What type of bond does selenium and bromine form?
Selenium and bromine can form an ionic bond, where selenium, a nonmetal, gains electrons to become a negative ion, and bromine, a halogen, loses electrons to become a positive ion.
