Whose most common oxidation state is -2?
Oxygen is the element whose most common oxidation state is -2. In fact, it only shows oxidation states of +2,+1 in compounds OF2, O2F2. It is because oxygen is the second most electronegative element behind Fluorine.
What is an element whose atoms can form a covalent bonds with another atom of the same element called?
The answer expected here is non-metal, and examples are carbon, chlorine, sulfur phosphorus. Metals have metallic bonds. However there are compounds where atoms of a metallic element form covalent bonds to other atoms of the same element.
Heaviest element whose atoms have more s electrons than p electrons?
The heaviest element whose atoms ave more s electrons than p electrons is helium. Helium is found in a wide variety of compounds, including water of H20, for instance.
What atom of an element with a different number of neutrons?
Isotopes.
Organic compounds have?
Organic compounds have carbon atoms bonded to hydrogen atoms, and may also contain other elements like oxygen, nitrogen, sulfur, or phosphorus. They are found in living organisms and are the basis of many biological processes. Organic compounds can range from simple molecules like methane to complex structures like proteins and DNA.

What is the same element whose nucleus contains different numbers of neutrons?
isotopes :D
What is a pure substance whose smallest unit is made up of atoms of more than one element?
it is mixtures not compounds
What is pure substance whose smallest unit is made up of atoms of more than one element?
it is mixtures not compounds
What two element's atomic numbers multiply to be 45?
Fluorine (whose atomic number is 9) and Boron (whose atomic number is 5).
What is a reactive metal whose compounds make up limestone chalk cement and the bones and teeth of animals milk is good nutritional source of this element?
calcium
How can you tell if an element has been reduced?
The reactant that reduces another atom
What is the metal with which it's most common oxidation state is -2?
There are no such metals whose common oxidation state is -2
What is a form of an element whose atoms have the same number of protons but different numbers of electrons?
An atom with a different number of electrons is called an ion.
Substance whose smallest unit is made up of more than one element and cannot be separated?
A compound is a substance whose smallest unit is made up of more than one element and cannot be separated by physical means. Compounds are formed when atoms of different elements chemically bond together in specific ratios.
What is an element whose atoms can form a covalent bonds with another atom of the same element called?
The answer expected here is non-metal, and examples are carbon, chlorine, sulfur phosphorus. Metals have metallic bonds. However there are compounds where atoms of a metallic element form covalent bonds to other atoms of the same element.
Two numbers whose sum is 58 and whose diffrence is 16?
The two numbers whose sum is 58 and whose difference is 16 are 21 and 37.
