True or false mendeleev also grouped elements that has similar properties?
Yes. Mendeleev did group elements in similar properties.
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.
Are elements with similar properties found in the same period or group on the periodic table True or False?
Yes. Its true that elements with similar properties are found in same group.
The number of valence shells are responsible for the makeup of the chemical properties of elements.?
true
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.
True or false The properties of a compound are limited to the individual properties of its constitutive elements?

When elements combine to form compoundstheir properties are an average of all elements in the compound?
This affirmation is not correct.
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.
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.
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 mendeleev also grouped elements that has similar properties?
Yes. Mendeleev did group elements in similar properties.
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
Do Compounds have properties uniquely different from the elements from which they are made?
false
Is it true that an alloy is a mixture of elements that has metallic properties?
false
Did Mendeleev group elements that had similar properties true or false?
It is true.
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.
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.
