In rutherford's gold foil experiment, most alpha particles passed through the gold foil without deflection and were detected on the screen. what caused the particles to pass through without any deflection? a. a large area of positively charged particles present in the gold foil. b. the extremely high speed of the alpha particles passing through the gold foil. c. a small area of negatively charged particles present in the gold foil. d. empty space in the atoms present in the gold foil.

An atom consists of a positively charged nucleus in the centre

There are electrons around the nucleus which are negatively charged

Most of space around nucleus is empty.

Alpha particles are positively charged

Now in Rutherford's experiment when alpha particles are passed through gold foil, the alpha particles

a) will get rebound from center (repulsion from central positive nucleus)

b) most of them get deflected as most of the part of atom is empty (no charged particle)

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
