(26) All atoms area...<span><span>with the number of protons equaling the number of electrons
</span>(27) </span>The particles that are found in the nucleus of an atom are...<span> protons and neutrons.
(28) </span>As a consequence of the discovery of the nucleus by Rutherford, which model of the atom is thought to be true?...<span>Protons. electrons, and neutrons are evenly distributed throughout the volume of the atom.
(29) </span>The nucleus of an atom is...<span>the central core and is composed of protons and neutrons</span>.
Answer: 1 mole ➡️ 6.022×10²³ atoms of si.
X mole ➡️ 2.8×10²⁴ atoms of si.
X = 2.8×10×10²³/6.022×10²³
= 28/6.022
= 4.65 moles.

The number is is surely 1
Ionization Energy: DOWN a Group: Ionization energy DECREASES as you go DOWN a Group because the farther the valence electrons are from the nucleus (pulling power of the protons) the less energy it costs another atom to steal them
