because they tend to lose electrons

What type of chemical reaction classes always involve oxidation?
The combination of two elements (a metal and a nonmetal) is always a redox reaction.
What kind of reaction is metal oxide plus nonmetal oxide æ ternary salt?
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."
Which element always exists in monatomic form?
neon, a noble gas
What is the overall charge of an ionic compound?
it is always equal to zero.The overall charge of a formula unit for an ionic compound is zero. The numbers of positive and negative ions are such that the sum of the positive charges and the negative charges is zero.
How can eletronegativity be used to distinguish between an ionic bond and a covalent bond?
If electronegativity varies by more than 1.4 then you are most probably looking at an ionic bond. A variance less than 1.4 means, usually a covalent bond can be formed. This is a rule of thumb and is not always reliable. Metal to nonmetal; ionic. nonmetal to nonmetal; covalent.

What is the most abundent metalloid in the Earth's crust?
Aluminum!!!!!=D ================== Nope - aluminum is almost always classified as a metal, not a metalloid. The most abundant metalloid is silicon - which, incidentally is about 3 times as abundant as aluminum.

This type of anion is called an "oxyanion" or the "anion of an oxyacid."
What happens when atoms form a covalent bond?
a) Must include a metal and a nonmetal b) Must be of different elements c) Are always of the same element d) Are always two metals Need Answer! :( D) Are always two metals. a) is for ionic compounds b) is for nonpolar covalent bonds c) same as nonpolar covalent bonds b) Must be of different elements:)

Is Rn radioactive nonmetals?
Yes, Rn is radon a radioactive nonmetal. But the symbol Rn does not stand for "radioactive nonmetal." Rn Radon has no stable isotopes, so yes it is always a radioactive nonmetal.
Is a metalloid always a synthetic metal?
i am reading about it, and it seems that no im not 100% only 4%
Does the first element in a binary compound have a charge?
hey i am in chem. now and this is a question on my worksheet my notes said that compound composed of 2 different element the total charge ot the cations = total charge of anions so if it helps i put yes they are always ionic but i gused so good luck to you

neon, a noble gas

Is carbon a metalliod?
That is a good question, and different sources say different things. Carbon has characteristics that would fit both answers. This is what the Princeton site has to say: Some allotropes of elements exhibit more pronounced metal, metalloid or non-metal behavior than others. For example, for the element carbon, its diamond allotrope is clearly non-metallic, but the graphite allotrope displays limited electric conductivity more characteristic of a metalloid. Phosphorus, selenium, tin, and bismuth also have allotropes that display borderline behavior. It is sometimes considered a metalloid, but not always.
Why does boron not always continue the Period 2 pattern of reacting by losing electrons?
because its a metalloid and the rest are all metals
