Which of the following statements most accurately describes the difference between ionic bond and covalent bond?
Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.
Which of the following statements is NOT a part of John Dalton's atomic theory?
During a chemical reaction, atoms can change their identities.
Which of the following are transferred or shared when two atoms react chemically Protons neutrons electrons photons?
When atoms react, electrons are shared or transferred.
When two atoms share a pair of electrons the bonding is referred to as what?
Yes A Nonmetal covalent bond is formed when electrons are shared between atoms, visit the following link.
Which statements about the octet rule is are true?
The bolded statements are true:1. The octet rule can be violated. 2. Atoms are most stable when their atomic number is divisible by 8.3. All free atoms contribute eight valence electrons to form molecules.4. Only the oxygen atom can have an expandable octet.5. In order to obey the octet rule, some atoms have to share more than one pair of electrons.

Which of these statements is false all neutrons are alike all electrons are alike all protons are alike all atoms are alike?
True statements: All neutrons are alike, all electrons are alike, all protons are alike (All atoms of a given isotope is only alike). False statement: All atoms are alike All atoms are not alike as they may vary in the number of protons / electrons / neutrons.
What determines whether or not an atom reacts with other atoms is it the electrons on the first shell or the second?
valence electrons or the electrons on the outer most shell.
Which of the following statements about monosaccharide structure is true?
Monosaccharides can be classified according to the spatial arrangement of their atoms.
When two atoms share a pair of electrons the bonding is referred to as what?
Yes A Nonmetal covalent bond is formed when electrons are shared between atoms, visit the following link.
What determines whether or not an atom will react with other atoms?
depends on the charges, either negative or positive

How are the electrons of atoms involved when a chemical change takes place?
The Valence electrons of an atom are shared or swapped (depending on whether it is a ionic or covalent bond)
Does whether or not charges will move in a material depend partly on how tightly they are held in the atoms of the material?
It depends on whether the charges are free to move. There are two ways in which charge can move through a substance. Ionic substances are made of positive and negative ions. In a solid they have fixed positions, but in liquids and gases they can move around. Ions are atoms (or groups of atoms) which have gained or lost electrons. How tightly their electrons are held has no effect here as it's the whole ion which moves. The second situation where charges can move is when electrons are in delocalized bonds. In most substances the electrons are in orbitals associated with one atom or a small group of atoms. In metals, some electrons are in large orbitals which are shared by all the atoms, so the electrons (which are charged) can move freely through the whole metal. In this situation, the delocalized electrons can be thought of as not held by individual atoms, but they are still held by the assemblage of atoms. So the assertion in the question has elements of being right, but it's not the degree to which the electrons are held, but whether or not they are delocalized.
What The key to whether or not an atom bonds with another atom depends on?
the amount of electrons available on the outer shells of the atoms
