PERIODIC TABLE TRENDS
The number of rows in the Periodic Table gives us the following information about the atoms
What is NUMBER OF ENERGY LEVELS
Three types of bonding
Ionic
Covalent
Metallic
This is the weakest type of IMF
What is London Dispersion Force?
Smallest particle that makes matter
what is THE ATOM
Number of centimetres in a metre
what is 100 cm
The number of electrons in the atom´s outermost energy level is called
what is THE VALENCE ELECTRONS
This type of bond forms when two atoms share electrons.
What is COVALENT BOND?
This intermolecular force occurs between permanent dipoles in polar molecules, where the positive end of one molecule attracts the negative end of another.
What are DIPOLE-DIPOLE forces?
These particles are found inside the nucleus
what are PROTONS & NEUTRONS?
This planet is known as the Red Planet because its surface contains iron oxide (rust).
What is MARS?
States that atoms lose, gain or share electrons to have a sfull set of valence electrons
what is OCTET RULE
This type of covalent bond occurs when electrons are shared equally between two atoms with similar electronegativities.
What is a NONPOLAR COVALENT BOND?
This special type of dipole–dipole interaction occurs when hydrogen is bonded to nitrogen, oxygen, or fluorine.
What is HYDROGEN BOND?
Einstein equation that shows that matter can be converted into energy and energy can be converted into matter
E = mc2
This scientist developed the theory of evolution by natural selection, published in On the Origin of Species in 1859.
Who is Charles Darwin?
As you go from left to right across a period, ELECTRONEGATIVITY increases because...
The larger the number of protons, the stronger the attraction between the nucleus and the electrons
This property measures an atom’s ability to attract electrons in a chemical bond and helps determine whether a bond is polar.
what is ELECTRONEGATIVITY?
This property of substances generally increases when intermolecular forces become stronger, because more energy is required to separate the molecules.
What is BOILING POINT?
Atoms gain or lose electrons because
what is to achieve a stable, lower-energy status
This international organization, founded in 1945 after World War II, was created to promote peace and cooperation among countries.
What is the UN? United Nations
The radius of elements increases down a family (column) because
Increased number of energy levels=electrons are farther from the nucleus
These intermolecular forces explain why alcohols like ethanol dissolve easily in water, unlike hydrocarbons.
What is HYDROGEN BONDING?
This molecule has unusually high boiling point compared with similar molecules because of strong hydrogen bonding.
What is WATER (H2O) ?
The higher values of BOND ENTHALPY
Means the STRONGER the BONDS
