1.602×10^-19
Avogadro's number, 6.022×10²³, is the number of atoms, molecules, or particles in one mole of a substance. This constant enables chemists to convert between countable particles and measurable mass. It is fundamental to stoichiometry. For further details, see Chemistry Explained on Avogadro's Number.
Which type of chemical bond involves the sharing of electron pairs between atoms?
Ionic bond
Covalent bond
Metallic bond
Hydrogen bond
Covalent bonds form when atoms share pairs of electrons, allowing each atom to attain a full valence shell. These bonds are common in organic molecules and gases like O? and N?. Bond strength and polarity depend on the atoms involved. More at Britannica on Covalent Bonds.
Which element has the atomic number 1?
Helium
Hydrogen
Lithium
Beryllium
Hydrogen, with atomic number 1, is the lightest and most abundant element in the universe. Its single proton and electron make it the simplest atom. It plays a vital role in chemistry, astrophysics, and energy applications. Read more at Chemicool on Hydrogen.
Which component of blood is primarily responsible for clotting?
Red blood cells
White blood cells
Platelets
Plasma
Platelets, or thrombocytes, are cell fragments in blood that initiate clot formation to stop bleeding. They aggregate at injury sites and release chemicals that aid in the clotting cascade. Proper platelet function is essential for wound healing. For more, see Britannica on Platelets.
What phenomenon explains the bending of light when it passes from one medium to another?
Reflection
Refraction
Diffraction
Dispersion
Refraction is the change in direction of a wave passing from one medium to another due to a change in its speed. In optics, this causes light to bend when entering water or glass. The degree of bending depends on the refractive indices of the media. Learn more at Britannica on Refraction.
Which particle mediates the strong nuclear force in the Standard Model?
Photon
Gluon
Graviton
W boson
In the Standard Model of particle physics, gluons are the gauge bosons that mediate the strong nuclear force, binding quarks together to form protons and neutrons. They carry the color charge associated with quantum chromodynamics. Understanding gluons is essential for high-energy physics. For details, see Britannica on Gluons.
Which law relates pressure, volume, and temperature for an ideal gas?
Boyle's law
Charles's law
Ideal gas law
Avogadro's law
The ideal gas law, PV = nRT, combines Boyle’s, Charles’s, and Avogadro’s laws into one equation relating pressure (P), volume (V), amount of gas (n), ideal gas constant (R), and temperature (T). It accurately describes the behavior of ideal gases under many conditions. Read more at Britannica on the Ideal Gas Law.
Which principle states that no two electrons in an atom can have identical quantum numbers?
Heisenberg uncertainty principle
Pauli exclusion principle
Law of conservation of energy
Schrödinger equation
The Pauli exclusion principle, formulated by Wolfgang Pauli in 1925, asserts that no two electrons in the same atom can possess identical sets of all four quantum numbers. This rule explains the structure of electron shells and the periodic table. It is fundamental to quantum mechanics. More at Britannica on the Pauli Exclusion Principle.
