A. a bond that forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
B. a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
C. a strong bond between two atoms that share their elections
D. a molecule containing a very large number of atoms, such as a protein, nucleic acid, lipid, or carbohydrate
Why does ice float?
A. As water freezes, it expands and its density decreases.
B. As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
C. As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
D. As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Atom
A. a land region on the earth’s surface covered by biological communities that group under the same climatic patterns like rainfall and temperature.
B. the descriptive and conceptual findings collected through questionnaires, interviews, or observation
C. a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
D. an element that remains unchanged or unaffected by other variables. It’s used as a benchmark or a point of comparison against which other test results are measured.
