Science Chemical Bonds Flashcards
They are positively charged particle
Protons
Are negatively charged particles
Electrons
Has no electrical charge and is neutral
Neutrons
The smallest unit of indivisible particle and is the building block of chemistry
Atom
The version of an atom where atoms are arranged in different combinations to create different compounds
John Daltons Model 1808
Negative electrons are stuck inside a positively charged pudding
Plum Pudding Model 1904 (JJ Thompson)
Atoms have a positively charged nucleus at the center. Aside from electrons, atoms are just open space.
Nuclear Model 1911 (Ernet Rutherford)
Electrons that spin around the central nucleus in an orbit.
Bohr’s Model 1913 (Niels Bohr)
Electrons sketching out different shapes around the nucleus are orbitals.
Quantum Mechanical Model 1920 (Erwin Schrodinger and Group)
What are electrons that occupy the highest energy or the outer ring of an atom
Valence Electrons
What are the max electrons of these sublevels. S=, P=, D=, F=
S = 2, p = 6, d = 10. f = 14
It was proposed by Gilbert Newton Lewis and is used to emphasize the valence electrons of an atom
Lewis Electron Dot Symbol (LEDS)
The rule that requires atoms to have 8 valences electrons to attain stability
Octet Rule
Refers to the attraction of two elements with opposite charges and when a metallic element reacts with a nonmetallic element. It is also the transfer of electrons
Ionic Bonds
Is Titanium a metal (Check Identification of metals and non-metals)
It is a metal
Is carbon a metal (Check Identification of metals and non-metals)
It is not
An atom or molecule that carries an electric charge
Ions
Positively charged ion
Cation
Negatively charged ion
Anion
Sharing of electrons between two non-metals
Covalent Bonds
Happens when there is only one bonding pair of electrons
Single Bond
Two bonding electron pairs or two atoms with four shared electrons
Double Bond
Three bonding electron pairs or six electrons shared by two atoms
Triple Bond
Identify the three things that can be seen in the electron configuration
- Main energy level
- Energy sublevel
- Number of electrons
Identify the three conditions that need to be met in order for bonding to be considered an ionic bond.
- Bonding between a metal and nonmetal
- Opposite charges
- Transfer of electrons
The two conditions that must be met in order for a bonding to be considered a covalent bond
- Sharing of electrons
- Bonding between a nonmetal and nonmetal
