Fill In The Blank With Correct Term Related To Chemistry Of Atoms Quiz

Protons, neutrons, and electrons are the three main subatomic particles that make up an atom. Positrons, photons, and muons are different types of particles that are not typically found within atoms.

The nucleus of an atom contains protons and neutrons, which account for most of its mass. Electrons, while moving around the nucleus, have very little mass in comparison.

Protons and electrons have equal but opposite charges, and in a neutral atom, the number of protons equals the number of electrons. Neutrons are neutral particles found in the nucleus, positrons are positively charged antimatter particles, and quarks are subatomic particles that make up protons and neutrons.

Isotopes of an element have the same chemical properties due to their identical electron configurations, even though they may vary in mass. This is why chemical properties are used to distinguish between elements, rather than physical or natural properties.

The correct answer is IONIC because an ionic bond is formed when electrons are transferred from one atom to another, resulting in oppositely charged ions being held together by electrostatic forces. Covalent bonds involve sharing of electrons, hydrogen bonds are a weaker type of interaction, and metallic bonds occur in metals where electrons are delocalized.

In a water molecule, the oxygen atom attracts the shared electrons more strongly than the hydrogen atoms, creating a partial negative charge near the oxygen and partial positive charges near the hydrogen atoms, making the water molecule polar.

The stomach produces hydrochloric acid to help break down food for digestion. Enzymes, hormones, and mucus also play important roles in the digestive process, but acid is specifically responsible for breaking down food particles.

The pH scale measures the concentration of ions in solution, specifically the concentration of hydrogen ions (H+) in the case of acidic solutions and hydroxide ions (OH-) in the case of basic solutions.

Complex carbohydrates are made up of multiple monosaccharide units, similarly, polymers are made up of repeating monomer units.

In a chemical reaction, reactants are the initial substances that undergo the reaction to form products. Catalysts are not changed by the reaction and do not become part of the products. Intermediates are compounds formed in the middle of a reaction but are not the final products.

In chemical reactions, endothermic reactions ABSORB energy from their surroundings in order to occur. If a chemical reaction does not have a source of energy to ABSORB, it will not occur.

Enzymes are typically named by adding the suffix -ASE to the substrate or type of reaction they catalyze. This is a common naming convention in biochemistry.

Electrons are the negatively charged subatomic particles in an atom, while protons are positively charged, neutrons are neutral, and positrons are positively charged antimatter particles.

Protons and neutrons are located in the nucleus of an atom, while electrons are found in the electron cloud surrounding the nucleus. The outer shell refers to the electron orbitals, and cytoplasm is a term used in cell biology, not atomic structure.

A molecule is a group of atoms held together by covalent bonds. A cell is the basic structural and functional unit of all living organisms. An element is a pure substance made of only one type of atom. A compound is a substance made of two or more elements chemically bonded together.

Sodium chloride (NaCl) is composed of sodium (Na) and chlorine (Cl) atoms that are chemically bonded together, making it a compound. An element consists of only one type of atom, a mixture is a combination of different substances that are not chemically bonded, and ionic refers to the type of bond formed between sodium and chloride ions in the compound.

Covalent bonds form when two atoms share electrons, while ionic bonds involve the transfer of electrons, hydrogen bonds are formed between a hydrogen atom and an electronegative atom, and metallic bonds occur in metals where electrons are shared among many atoms.

Weak chemical attractions between polar molecules are Hydrogen bonds, which are formed between a hydrogen atom in one polar molecule and a highly electronegative atom in another polar molecule.

The correct answer is 'IONIC' as the attraction between oppositely charged ions results in ionic bonding, where electrons are transferred from one atom to another to create ions with opposite charges.

Water has a high specific heat capacity, which means it heats and cools slowly compared to other substances.

Cohesion refers to the attraction between molecules of the same substance, causing them to stick together. Adhesion is the attraction between different substances. Gravity is the force that pulls objects towards each other. Surface tension is the property of a liquid that allows it to resist an external force.

Water is considered the medium in which most cellular events take place due to its unique properties and essential role in biological processes.

Substances with a pH lower than 7 are considered acidic because they have a higher concentration of hydrogen ions.

pH is a measure of how acidic or basic a substance is. Substances with a pH greater than 7 are considered basic, while substances with a pH less than 7 are considered acidic. A pH of exactly 7 is considered neutral.

The pH scale specifically measures the concentration of hydrogen ions in solutions, which determines the acidity or alkalinity of the solution.

Lipids are classified as nonpolar molecules due to their lack of positive and negative poles, making them hydrophobic and unable to dissolve in water.

Long chains of nucleotides are known as nucleic acids, which are the fundamental building blocks of DNA and RNA. Proteins are made up of amino acids, not nucleotides.
