Gallium has two naturally occurring isotopes. The mass of gallium-69 is 68.9256 amu and it is 60.108% abundant. The mass of gallium-71 is 70.9247 amu and it is 39.892% abundant. What is the atomic mass of gallium?
To find the average ($"A"_r$) of an element, given the percentage rarities of its , simply multiply each isotope's $"A"_r$ by its percentage that is expressed as a decimal...

What are examples of metals, non-metals and metalloids?
Metals lose electrons to become positive ions. The elemental metals bond using which uses a sea of electrons to bond unlimited numbers of atoms together. Most are metals. magnesium, iron,...

Why do metals tend to lose electrons and nonmetals tend to gain electrons when forming ions?
Nonmetals tend to gain electrons in order to achieve a full outer shell, so they are said to have high electronegativities. Alkaline metals, for example, would find it much...

What is the difference between metals and metalloids?
Metals---these are generally hard( Na and K are exceptions),lustrous,malleable,ductile,conducting and electron giving elements. Non metal---reverse of metals.(eg; they're generally soft,non-lustrous etc.) Metalloids--these are the elements which show properties of...

What type of bond is formed when nonmetals combine with other nonmetals?
Nonmetals have relatively high electronegativity, so both atoms in the bond want to keep the electrons that are being shared between them. This creates a covalent bond. If one...

A compound is broken down into 34.5 g of element A, 18.2 g of element B, and 2.6 g of element C. What is the percent (by mass) of each element?
$%A$ $=$ $(34.5*g)/(34.5*g+18.2*g+2.6*g)xx100%=62.3%$ $%B$ $=$ $(18.2*g)/(34.5*g+18.2*g+2.6*g)xx100%=33.0%$ $%C$ $=$ $(2.6*g)/(34.5*g+18.2*g+2.6*g)xx100%=4.70%$ That is $%" element"$ $=$ $"Mass of element"/"Mass of compound"xx100%$ $"Mass of compound"$ is clearly the SUM of the constituent ....
