SEMMELWEIS ENTRANCE EXAM MEDICINE
BIOLOGY TEST BANK 2026 UPDATED
QUESTIONS AND ACCURATE ANSWERS
GRADED A+
⩥ Avogadro's number. Answer: number of representative particles in a
mole, 6.02 X 10^23
⩥ Basic structures of atoms. Answer: There is a nucleus in the center
surrounded by an electron cloud or field
⩥ Quantum numbers. Answer: Quantum numbers describe values of
conserved quantities in the dynamics of a quantum system. In the case of
electrons, the quantum numbers can be defined as "the sets of numerical
values which give acceptable solutions to the Schrödinger wave equation
for the hydrogen atom"
⩥ Common compounds. Answer: Water (H2O), table salt (NaCL);
carbon dioxide (CO2); baking soda (NaHCO3); carbon monoxide (CO);
sand or glass (SiO2)
⩥ Periodic properties. Answer: chemical or physical properties that vary
among elements according to trends that repeat as atomic number
increases
, ⩥ What are the periodic properties?. Answer:
⩥ Element (on periodic table). Answer:
⩥ Atomic number is the same as. Answer: number of protons
⩥ Atomic mass is the same as. Answer: Number of protons and neutrons
⩥ Different types of chemical bonding. Answer: metallic, covalent, ionic
⩥ What is covalent bonding and how does it work?. Answer: when
atoms share one or more pairs of electrons. They have similar
electronegativities
⩥ What is ionic bonding?. Answer: when atoms transfer electrons. Large
difference in electronegativity
⩥ Examples of ionic bonds. Answer: NaCl
Cs2O
MgO
NH4NO3
