True or false A compounds properties depend on the elements it contains and how they are compare?
We can say that this is true to some extent.We must all agree that the properties of a compound DOES depend on the elements it contains since a variation in the elements changes the properties of the compound.However, what we must remember is that the properties of the compound does NOT depend on the properties of the elements that make up the compound.A simple example is water, made of hydrogen and oxygen. Water is very different from the elements indeed.
True or false The properties of a compound are limited to the individual properties of its constitutive elements?

A given compound usually contains the same relative number of atoms of its various elements true or false?
Today this affirmation is not generally valid.
The first element in a compound is positive and the second one is negative.?
false
A diatomic element may consist of two atoms of the same element or one atom of two different elements?
false
When a compound is created it can be broken down into its original parts. true or false?
The statement is true, if by "original parts" the questioner means "original elements"; this is part of the definition of a compound.
A compound can consist of one element?
False, because a compound is a pure chemical substance consisting of two or more different chemical elements. It can be separated into simpler substances by chemical reactions.
Is it true or false when a compound is formed by two or more atoms of different elements joining the outer electron shell of the compound is completely filled with electrons.?
true
True or False an atom is the smallest part of a compound that may still be identified as the compound?
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
When elements combine to form compoundstheir properties are an average of all elements in the compound?
This affirmation is not correct.
True or false a compound can only have one element?
false because a compound has to have two elements to become a compound so if it's just one element it's just a element.
There are 90 different elements?
False
Is a compound formed by two positive elements?
No, two positives are repelling, not attracting. No. Compounds are formed by two or more different elements. An ionic compound is formed by the attraction between two oppositely charged ions. Molecular compounds are formed by the sharing of electrons between atoms, which is called a covalent bond.
Is it true of false that the energy of an ionic compound is higher than that of the separate elements that formed it?
I believe that it depends on the elements that you are combining or seperating.
Can compounds have only one element?
false a compound is made up of two or more elements.
Is an element composed of two or more compounds True or false?
False. A compound consists of 2 or more elements that combine chemically.False. You have that backwards. This might help to remember it - elements are elemental while compounds are compoundedfrom elements.
Mixtures have strong chemical bonds true or false?
Not between the different components of a mixture, no.
