Which of the following is an element?
Sugar
Water
Carbon
Salt (NaCl)
An element is a pure substance made of only one type of atom, and carbon fits this definition as it consists solely of carbon atoms. Water (H2O), salt (NaCl), and sugar (C12H22O11) are compounds composed of two or more elements chemically bonded together. Every element has its own atomic number and unique properties, which for carbon includes its ability to form four covalent bonds. Learn more about carbon at .
What is the smallest particle of an element that retains chemical properties?
Electron
Molecule
Compound
Atom
The atom is the smallest unit of an element that retains all the chemical properties of that element. Molecules are made of two or more atoms bonded together, while electrons are particles within the atom and compounds are substances formed from multiple elements. Therefore, the atom is the fundamental building block of matter for elements. Read more at .
Which group of subatomic particles has a positive charge?
Neutrons
Protons
Photons
Electrons
Protons are subatomic particles with a positive electrical charge found in the nucleus of an atom. Electrons carry a negative charge and orbit the nucleus, while neutrons have no charge, and photons are particles of light. The number of protons determines the element's identity and atomic number. More information is available at .
What is the atomic number of an element?
Number of neutrons
Number of electrons
Mass number
Number of protons
The atomic number of an element is defined as the number of protons in the nucleus of its atoms. Although electrons and neutrons also contribute to atomic properties, they do not define the element's position on the periodic table. The mass number, which includes protons and neutrons, differs from the atomic number. For further reading see .
What defines an isotope of an element?
Same number of protons, different number of neutrons
Same mass number, varying number of electrons
Same number of electrons, varying number of neutrons
Same number of neutrons, different number of protons
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, resulting in different mass numbers. This difference in neutron count does not affect the chemical behavior but does change the atomic mass. Options with the same neutrons or electrons but varying protons define different elements or ions, not isotopes. Learn more about isotopes at .
Which element has an electron configuration ending in 3p5?
Chlorine
Sulfur
Argon
Fluorine
An electron configuration ending in 3p5 corresponds to chlorine, which has 17 electrons in total and places five of them in the 3p subshell. Fluorine ends in 2p5, argon ends in 3p6, and sulfur ends in 3p4. The superscript numbers indicate the count of electrons in that subshell. More details can be found at .
What type of chemical bond is formed when electrons are shared between atoms?
Ionic bond
Van der Waals forces
Metallic bond
Covalent bond
A covalent bond forms when two atoms share one or more pairs of electrons, typically between nonmetals. In contrast, ionic bonds involve the transfer of electrons, metallic bonds allow delocalized electrons, and van der Waals forces are weak intermolecular attractions. Covalent bonding leads to molecule formation, such as in oxygen gas (O2) and water (H2O). Learn more at .
Which of these elements has the smallest atomic radius?
Rubidium
Sodium
Lithium
Potassium
Atomic radius decreases across a period from left to right due to increasing nuclear charge pulling electrons closer to the nucleus. Among lithium (Li), sodium (Na), potassium (K), and rubidium (Rb), lithium is the leftmost in period 2 and hence has the smallest atomic radius. As you go down the group, atomic size increases. For more on periodic trends see .
Given that chlorine has two stable isotopes: 75% Cl-35 and 25% Cl-37, what is its average atomic mass?
37.0 amu
35.5 amu
35.0 amu
36.0 amu
The average atomic mass of chlorine is calculated by taking the weighted average of its isotopes: about 75% Cl-35 and 25% Cl-37. Thus, the atomic mass = (0.75 × 35) + (0.25 × 37) = 35.5 amu. This weighted calculation accounts for natural abundance variations. More on isotopic masses at .
What is the molecular geometry of methane (CH4)?
Octahedral
Linear
Tetrahedral
Trigonal planar
Methane (CH4) has four hydrogen atoms symmetrically arranged around a central carbon atom, creating a tetrahedral molecular geometry. This shape arises due to electron pair repulsion in the valence shell of carbon, as explained by VSEPR theory. Alternative geometries like trigonal planar or linear do not apply when four bonding pairs exist. Read more at .
What is the molar mass of calcium carbonate (CaCO3)?
88.02 g/mol
100.09 g/mol
104.09 g/mol
97.09 g/mol
Calcium carbonate (CaCO3) has a molar mass equal to the sum of one Ca (40.08 g/mol), one C (12.01 g/mol), and three O (3 × 16.00 g/mol) atoms, totaling approximately 100.09 g/mol. Calculating each component ensures precise stoichiometric conversions in chemical reactions. Alternative values like 104.09 or 88.02 g/mol arise from miscounted atoms. For calculation guidance see .
According to the Aufbau principle, which orbital is filled immediately after the 4s orbital?
3d
4p
2p
5s
According to the Aufbau principle, after filling the 4s orbital, electrons begin to fill the 3d subshell. The 4s orbital is lower in energy than the 3d for the first transition series, so it fills first. Subsequent electrons enter 3d before moving to 4p. For a deeper dive see .
Which of the following compounds exhibits hydrogen bonding?
CH3OH
CH3CHO
CH3Cl
CH3CH3
Hydrogen bonding occurs when hydrogen is covalently bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine. Methanol (CH3OH) contains an -OH group capable of forming hydrogen bonds with other molecules. Neither ethane (CH3CH3), acetaldehyde (CH3CHO), nor chloromethane (CH3Cl) have H directly attached to oxygen, nitrogen, or fluorine. More on hydrogen bonds at .
What is the formal charge on the nitrogen atom in the ammonium ion (NH4+)?
0
+2
-1
+1
In the ammonium ion (NH4+), nitrogen forms four covalent bonds and has no lone pairs, which gives it a formal charge of +1. Formal charge = valence electrons (5 for N) minus non-bonding electrons (0) minus half the bonding electrons (4) = +1. This positive charge is delocalized over the ion, making NH4+ a stable cation. For further examples see .
