The Chemical Basis of Life - Basic Chemistry Matter: anything that occupies space and has mass (solid, liquid, or gas) Mass: amount of matter in an object Weight: gravitational force acting on object Element: simplest form of matter Example: C, H, O, N, Ca, K, Na, Cl Atom: smallest particle of an element contains protons, electrons, and neutrons. Subatomic Particles Proton: positive charged particle located inside the nucleus Neutron: neutral charged particle located inside the nucleus Electron: negative charged particle located outside the nucleus Atomic Number and Atomic Mass Atomic number: the number of protons in each atom Mass number: the number of protons and neutrons in each atom Chemical bonds occur when outermost electrons (valence shell electrons) are transferred or shared between atoms Types of chemical bonds Ionic Covalent Hydrogen Ion: a charged atom formed because of a donation or gain of an electron(s) Example: Na+, Cl− Ionic bonding occurs when there is an attraction between two oppositely charged ions Example: NaCl Covalent bonding occurs when atoms share one or more pairs of electrons Example: hydrogen molecule (H2) Polar covalent bonds form when there is an unequal sharing of electrons between atoms of the bond Example: water (H2O)
Understand the Problem
The question provides an overview of basic chemistry concepts related to the chemical basis of life, including definitions, properties of matter, subatomic particles, atomic number, atomic mass, and types of chemical bonds. It aims to summarize fundamental principles of chemistry essential for understanding biological processes.
Answer
Matter is anything that occupies space and has mass.
Matter is anything that occupies space and has mass.
Answer for screen readers
Matter is anything that occupies space and has mass.
More Information
Matter can exist in different states, such as solid, liquid, and gas.
Tips
A common mistake is to confuse weight with mass. Mass is the amount of matter in an object, whereas weight is the gravitational force acting on that mass.
