The fundamental unit of life is the correct answers e. cell. Heterotrophs obtain their energy from correct answers c. other organisms. The initial accumulation of oxygen in the atmosphere was the result of photosynthesis from an organism most like modern correct answers a. cyanobacteria (blue green algae). Ozone is important to life on Earth because it correct answers c. blocks much ultraviolet radiation. Eukarya include correct answers e. All of the above The part of the atom tha...

Chemistry Cumulative Review Latest Update Graded A+ Electronegativity The tendency of an atom to attract electrons in a chemical bond. It is not directly measurable. Metals have low electronegativity, meaning they do not hold onto electrons tightly and often lose them in reactions. Nonmetals have high electronegativity, meaning they hold onto electrons strongly and often gain electrons from other elements. Covalent Bond The sharing of electrons between two nonmetal atoms. ...

UTK CHEM122 EXAM 2 QUESTIONS WITH 100% GUARANTEED PASS (LATEST UPDATES) What determines the polarity of a molecule? - Answer-Electronegativity Octet Rule - Answer-When forming compounds, atoms tend to achieve the electron configuration of a noble gas (8 electrons) Duet Rule - Answer-Hydrogen and Helium only want two electrons Nonpolar Covalent Bond - Answer-Equal sharing of electrons Polar Covalent Bond - Answer-Unequal sharing of electrons Ionic Bond - Answer-Giving or taking ...

the octet rule is correct answers when atoms bond, they lose, gain, or share electrons to get a full outer (valence shell) energy level which has 8 electrons to start a lewis structure, pick the atom that is usually correct answers the least electronegative (except H) the first in the formula lowest group number if the two atoms are in the same group correct answers select the one in the highest period To avoid the wrong number of electrons you should correct answers count the electro...
