Answer:
atomic orbital
Explanation:
Atoms are made of three sub-atomic particles, electron, proton and neutron.
Protons and neutrons are present in the core of the atom in a very small zone called nucleus. Nucleus is positively charged.
Electrons are present around the nucleus. Electrons present outside the nucleus are also termed as electron cloud. Region outside the nucleus where probability of finding an electron is maximum is termed as atomic orbital. Four basic types of orbitals are present around the nucleus which are
s-orbital
p-orbital
d-orbital
f-orbital
Electrons present in same orbitals have same energy. Therefore, term is atomic orbital.
Answer:
A sample of salt has 1.74 moles of sodium chloride. how many formula units of the ionic compound are in the sample?
Explanation:
Given, 1.74 moles of NaCl.
Since one mole of NaCl consists of --- formula units.
Then, 1.74mol of NaCl contains how many formula units of NaCl?
formula units.
Hence, the given sample has 10.5x10^23 formula units.
