How many electrons are present in one mole of H2?
In one mole of H2, there are six electrons present. Two electrons are contributed by each hydrogen atom.
How many protons and neutrons and electrons are in H?
There are 1 proton, 0 neutron and 1 electron in H1.
Can the elements be divided into compounds such as iron?
You have this a little backwards.Compounds like water (H2O) can be divided into elements like Oxygen (O2) and Hydrogen (H2). Iron is also an element.There are 118 unique elements from which all matter on earth is derived from.The basic unit of an element is an atom.Atoms are made out of protons, neutrons, and electrons which uniquely identify the element that the atom is part of. Hydrogen atoms have 1 proton and can have 0, 1, or 2 neutrons. Helium atoms have 2 protons, and usually have 2 neutrons. Etc.The Protons and Neutrons are made out of Quarks.
Why do oxygen atoms look so different from hydrogen atoms?
Differences: * All atoms are made up of neutrons, protons and electrons. Each element has a different number of protons, but the number of neutrons and electrons can vary. Typically, a hydrogen atom has one Proton, one electron and no neutrons. Oxygen atoms have 8 protons, 8 electrons and 8 neutrons. * Most commonly, Hydrogen atoms form +1 ions by loosing an electron. Oxygen forms a -2 ion, through the gaining of two electrons. (To understand why this is, you need to understand the electric charges of protons and electrons). These are the most basic differences. Similarities: * Both elements are quite volatile and will react with most other reactive elements. * They are both diatomic molecules. This means that they will always come in pairs such as H2 and O2, (two hydrogen or oxygen bonded together). There are other differences, but in much more complicated chemistry.
What is the charge of an element with 3 protons and 3 electrons?
A proton has a positive charge and an electron has a negative charge. If you have 3 protons and 3 electrons, then: 3 positive + 3 negative then you have a sum total of: (+3) + (-3) which comes out to a total of: 0 You have a net charge of 0.
How many valance electrons in H2?
1
Can just the protons be the nucleus?
In the case of a normal hydrogen atom the nucleus is only one proton, there are no neutrons. However, every other atom and molecule (apart from H2) has at least one neutron in the nucleus.
How many electrons are present in one mole of H2?
In one mole of H2, there are six electrons present. Two electrons are contributed by each hydrogen atom.
How many protons and neutrons and electrons are in H?
There are 1 proton, 0 neutron and 1 electron in H1.
Is it true that each element consist of only one type of atom?
Yes, each element consists of only one type of atom in terms of atomic number, which is the number of protons in the nucleus. However, atoms of the same element can differ in mass number and are called isotopes. Mass number is the sum of protons and neutrons in the nucleus of an isotope. The numbers of neutrons can vary, so the mass number can vary.

When are the electrons and protons equal?
The covalent bond between the two atoms is nonpolar.

How many bonds and how many electrons in total does h2 share?
In an H2 molecule, each hydrogen atom shares one bond with the other hydrogen atom. This results in a total of 2 bonds and 2 electrons being shared between the two hydrogen atoms in the molecule.
What is the difference between H2 and H1 isotopes?
They have different numbers of neutrons and therefore different atomic masses. Hydrogen-2, with 1 protons and 1 neutron has an atomic mass of 2. Hydrogen-1, with 1 proton and no neutrons has an atomic mass of 1. (By the way, the accepted way of writing these symbolically if you can't use subscripts is to put the number first, vis: 2H)
What type of chemical bond occurs between atoms in molecules such as h2 ch4 nh3 h2 cch2 n2 cl2 and many large biological molecules?
covalent bonds --- sharing electrons
