Answer: An electron having a quantum number of one is closer to the nucleus
Explanation:
The Bohr model relies on electrostatic attraction between the nucleus and orbital electron. Hence, the closer an electron is to the nucleus the more closely it is held by the nucleus and the lesser its energy (the more stable the electron is and the more difficult it is to ionize it). The farther an electron is from the nucleus ( in higher shells or energy levels), the less the electrostatic attraction of such electron to the nucleus due to shielding effect. Hence it is less tightly held.
Answer:
Explanation:
Hello,
In this case, given that the mass of the product is 0.534 g, we can infer that the percent composition of tin is:
Therefore, the percent composition of oxygen is 6.4% for a 100% in total. Thus, with such percents we compute the moles of each element in the oxide:
In such a way, for finding the smallest whole number we divide the moles of both tin and oxygen by the moles of oxygen as the smallest moles:
Therefore, the empirical formula is:
Best regards.
It is the 2 pairs i really do not know but yea
Chlorophyll
<span>Chlorophyll is important for doing photosynthesis, as you probably know. It breaks down when its exposed to light, so during the long days of the year, new chlorophyll keeps being delivered to the leaves. Its expensive for the plant to make it, so before a plant loses its leaves, it stops making and delivering new chlorophyll. The old chlorophyll still breaks down, leaving behind the pigments that last longer. </span>
Answer:
Sodium chloride, on the other hand, contains ions; it is an ionic compound. CaO is correct.
