Calculate the net charge on a substance consisting of a combination of 7.01013 protons and 4.01013 electrons?

Because protons and electrons have the same magnitude of electric charge each, but of opposite signs, this charge would be 7.01013 - 4.01013 = 4. (Only one significant digit is given, and the question itself is suspicious, because fractional protons and electrons do not exist!)

Do atoms include molecules electrons elements and protons?
No. Atoms contain protons, neutrons and electrons. An element is a substance consiting of atoms with the same number of protons. A molecule is a particle consisting of two or more atoms covalently bonded to one another.
Are elements substances or mixtures?
A substance can be an element, a compound or a mixture. Sodium is a substance and also an element. It is a substance but consisting of only one type of atom. Sodium Chloride is a substance and also a compound. It is a substance but consists of two elements chemically combined and is thus also a compound. Sodium chloride and sand mixed together is a substance and also a mixture.
How do electrons help in transfer of heat energy?
when a substance is heated,the molecules in that substance get heat energy. we know that all of the molecule in the substance having electrons. when substance is heated. electrons becoming high energetic.and they move faster and also energy will propagate though out the substance
What type or reaction occurs when one substance donates electrons and other substance accepts those electrons?
It is a redox reaction.
What substance loses electrons with a rusty nail?
Iron lose electrons.
Is an element a combination of atoms?
No. An element is a substance consisting of only one type of atom.
Soil is a substance?
Soil is a substance; anything consisting of real physical matter is a substance.
A substance consisting of two or more elements in a fixed ratio.?
a chemical compound is a substance consisting of two or more elements in a fixed ratio.
Do atoms include molecules electrons elements and protons?
No. Atoms contain protons, neutrons and electrons. An element is a substance consiting of atoms with the same number of protons. A molecule is a particle consisting of two or more atoms covalently bonded to one another.
What is plasma star?
The Sun and all stars are made almost entirely of plasma, a gas-like substance consisting mainly of electrons, protons and helium ions. The combination of charged particles is what makes a plasma. They are sometimes called stellar plasmas. For more information, see: http://www.plasma-universe.com/
