What is an isotope?
Answer: An atom with the same number of protons but different number of neutrons
Isotopes are variants of an element with different neutron counts but the same proton count.
In a polar covalent bond, electrons are:
Answer: Shared unequally between atoms
In polar covalent bonds, electrons are shared but pulled more toward the more electronegative atom.
Which group on the periodic table contains the noble gases?
Answer: Group 18
Group 18 (the rightmost column) contains noble gases like helium, neon, and argon.
How many covalent bonds does carbon typically form?
Answer: 4
Carbon has 4 valence electrons, so it forms 4 covalent bonds to complete its octet.
What determines the chemical properties of an element?
Answer: The number of valence electrons
Valence electrons (outermost shell electrons) determine how an element bonds and reacts.
What type of bond holds water molecules to each other?
Answer: Hydrogen bond
Hydrogen bonds are intermolecular forces between water molecules, caused by the polarity of O-H bonds.
