Mass is the number of protons + number of neutrons. Because electrons don't have significant weight.
Table salt is sodium chloride mixed with small<span> amount of </span>potassium iodide (KI)<span>, </span>sodium iodide (NaI)<span> or </span>sodium iodate (NaIO₃)<span>.
Atomic level - sodium chloride (NaCl) has crystal cubic structure (</span>lattice-type arrangement)<span> with ionic bonds. Sodium is cation with charge 1+ and chlorine is an anion with charge 1-.
Macroscopic level - table salt is c</span>olorless crystal, soluble in water with high melting and boiling temperature..
I'm assuming A, but it says modern, so..
Answer:
Electrons- 95
Protons- 95
Neutrons-146
Explanation:
An atoms is made up of three fundamental particles; electrons, protons and neutrons,
Americium belongs to the f block in the periodic table. It is an actinide element.
An atom of Am-241 contains 95 protons, 95 electrons and 146 neutrons.
Answer:
p orbital.
Explanation:
Valence electrons are the electrons in an atom holding the very last orbital which is used in chemical bonding with other elements. Their existence could define the chemical properties of that atom.
During the first energy in ionization of an N2 molecule the molecular orbital from which the electron could be extracted is the only one with the highest energy level. Nitrogen has its outermost orbital (p) containing three valence electrons. Each orbital is only half filled, and thus it is unstable Thus, the electron mission must have been removed from p orbital.
