What is the advantage of using a structural formula over a molecular formula?
A molecular formula indicates the numbers of atoms of each element in the molecule, but a structural formula also indicates the arrangement of the atoms in the molecule. For example, H2O is the molecular formula for water, but H-O-H is the structural formula, showing how the hydrogen and oxygen atoms are arranged in the molecule.
What is the name given to pairs of atoms such as protium and deuterium?
Those are different isotopes of the same element. Different isotopes of the same element have the same number of protons, but a different number of neutrons. There are a little over 100 known elements, but over 3000 different known isotopes.
Why is uranium classified as a radioactive element?
That means that some of the atoms will decay over time.
How does an atom make up an element?
Uranium, Hydrogen, or Plutonium.
What is molecular orbitals extending over more that two atoms called?
Molecular orbitals extending over more than two atoms are called delocalized molecular orbitals. These orbitals involve the interaction of multiple atomic orbitals across a molecule, allowing electron density to be spread out over a larger region. This delocalization gives rise to unique bonding characteristics and contributes to the stability of the molecule.

What is a pure substance made up of the same kind of atoms called?
This describes an element. There are over a hundred elements in the physical world, and they are all categorized in the periodic table.

What is a molecule consisting of a large number of atoms?
They are still Molecules. However, specific names are given to different types of molecules, which may have 'millions'; of atoms in their structure. e.g. Enzymes ; Organic Catalysts. Polymers ; to make 'plastics etc., Proteins ; to make muscles. DNA ( Deoxyribonucleic Acid ; makes up the genetic system ). Ar just a few molecules with a very large number of atoms.

Which element makes up over 90 of the atoms in our galaxy?
Hydrogen is the element that makes up over 90% of the atoms in our galaxy. It is the most abundant element in the universe and plays a crucial role in the formation of stars and galaxies. In addition to hydrogen, helium is the second most abundant element, but its presence is significantly less than that of hydrogen. Together, these elements are fundamental to the structure and evolution of the cosmos.
How does an atom make up an element?
Uranium, Hydrogen, or Plutonium.
Why is the total electrical charge of a water molecule neutral?
there are no valence electrons left over after the two H atoms combine with the O atom.
How many neutrons does the atoms have?
Anywhere between zero, and over a hundred - it depends on the atom (on the element, and the isotope).
What is molecular orbitals extending over more that two atoms called?
Molecular orbitals extending over more than two atoms are called delocalized molecular orbitals. These orbitals involve the interaction of multiple atomic orbitals across a molecule, allowing electron density to be spread out over a larger region. This delocalization gives rise to unique bonding characteristics and contributes to the stability of the molecule.
What is delocalised electron?
Delocalisation is when electrons are not associated with one atom but are spread over several atoms. So the electrons are not directly bonded with any atoms but effectively 'float' above and below the molecule in electron clouds.
