Unit two Bonds
Cards in this deck (10)
- 1What is Chemical Bonds?Chemical bonds are when two or more electrons are attracted to the nuclei.
/
It is the electrostatic force that holds atoms in a molecule. - 2Why do chemical bonds form?They form when the atoms collide and the outermost electrons of the atoms come into contact with one another thenThe positively charged nucleus of each atom pulls on the valence electrons.
- 3What is electrostatic force?It is the force between charged particles.
- 4What is bond energy?It is the energy required to break a particle bond in a compound.
- 5What is bond length?It is the distance between the centers of two nonmetals/covalent bonds.
- 6What is needed to break chemical bonds and how?Energy is needed to break a chemical bond. Energy must be transferred to a strong bond to return its atom to zero potential energy
- 7What are covalent bonds?It is a chemical bond that forms when two atoms share their outmost electrons.
- 8What does the octet rule state?It states that atoms tend to bond in a way that they each have 8 electrons in their outer energy level, giving them the same electron configuration as a noble gas.
- 9What are the types of covalent bonds?singe covalent bonds
double covalent bonds
triple covalent bonds
coordinate covalent bonds - 10what do they each do?when two atoms they share two electrons
forms a
when two atoms share four electrons
when two atoms share six electrons
when one atom supplies both electrons for the bond
