SEMMELWEIS ENTRANCE EXAM MEDICINE
BIOLOGY SCRIPT 2026 TESTED QUESTIONS
WITH COMPLETE SOLUTIONS GRADED A+
⩥ What are atomic orbitals? Answer: regions where there is a high
probability of finding an electron
⩥ What are the first few electron configurations? Answer: 1s
2s, 2p
3s, 3p, 3d
4s, 4p, 4d, 4f
⩥ What are primary chemical bonds? Answer: ionic, covalent, metallic
⩥ What are secondary chemical bonds? Answer: 1. Hydrogen bonds
2. Van der Waals bonds
⩥ What are hydrogen bonds? Answer: Bonds between hydrogen atom
and atoms of the most electronegative elements (N, O, F)
⩥ What are Van der Waal's bonds? Answer: The first type is a result of
electrostatic attraction between two permanent dipoles
, The second type of Van der Waal's bond is formed due to temporary
dipoles
⩥ Properties of water Answer: • strong hydrogen bonds
• high heat capacity
• solvent
• needs a lot of energy to evaporate
• expands when freezes
• cohesion (sticks to itself)
• adhesion (sticks to other things)
⩥ What are the intermolecular forces in water? Answer: Hydrogen
bonds, dipole-induced dipole forces, and London dispersion forces
⩥ Ionization of water Answer: the transfer of a proton from one water
molecule to another to produce a hydroxide ion and a hydronium ion
⩥ What are the types of concentrations? Answer: mass concentration,
molar concentration, number concentration, and volume concentration.
⩥ What is the definition of pH? Answer: measure of hydrogen ion
concentration of a solution to determine acidity/basic
