Answer:
23 moles Oxygen × 6.02 × 1023 atoms = 1.3846 × 1025 atoms Oxygen.
Explanation:
Answer:
The answer to your question is Protons = 78, Neutrons = 117, Electrons = 76
Explanation:
¹⁹⁵Pt²⁺
Protons are equal to the atomic number, Platinum has an atomic number of 78 so the number of protons = 78.
The number of neutrons = Mass number - Number of protons
= 195 - 78
= 117
The number of electrons is equal to the number of protons - two, we know this because of the 2+ exponent next to the Platinum symbol.
Number of electrons = 78 - 2
= 76
Answer:that sugar dissolves faster in a warm liquid than in a cool
Explanation:
Molecular diffusion, often simply called diffusion, is the thermal motion of all (liquid or gas) particles at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles. Diffusion explains the net flux of molecules from a region of higher ... Diffusion of solvents,
Neutral atoms get smaller as you move across the periodic table from (left to right) because the atom increases in electrons. The more electrons, the bigger the effective nuclear charge (electron and proton attraction) and so basically the atom shrinks.
