Answer:
Here is your answer: Tin,
Explanation:
Which of the following elements probably has the most properties in common with lead (Pb)? Tin (Sn).
Answer is: it is not possible, because orbital (azimunthal) quantum number cannot be 2.
The principal quantum number (n) is one of four quantum numbers which are assigned to each electron in an atom to describe that electron's state.
For principal quantum number n=2:
1) azimuthal quantum number (l) can be l = 0...n-1:
l = 0, 1.
The azimuthal quantum number determines its orbital angular momentum and describes the shape of the orbital.
2) magnetic quantum number (ml) can be ml = -l...+l.
ml = -1, 0, +1.
Magnetic quantum number specify orientation of electrons in magnetic field and number of electron states (orbitals) in subshells.
3) the spin quantum number (ms), is the spin of the electron.
ms = +1/2, -1/2.
Iron is matter; since the smallest unit of matter is atoms, iron could be brokolen down into atoms. unlike iron, water is a molecule made from atoms that were chemically combined, so water could be broken down into molecules.
Answer:
- <u><em>The bag with no sunscreen held the most vibrant beads.</em></u>
Explanation:
<em>SPF</em> is the Sun Protection Factor. It indicates how long a person can stay out in the sun before his skin start burning. It is a factor that is multiplied by 15 minutes. SPF 30 means 30 times 15 = 450 minutes. SPF 70 means 70 times 15 = 1,050 minutes.
Thus, the bag covered in <em>SPF 30</em> <em>sunscreen</em> will raise its temperature faster than the bag covered in <em>SPF 70 </em>sunscreen. And the bag with <em>no sunscreen </em>will raise its temperature faster than the other two.
The higher the temperature the more vibrant the particles that consititute the substances, thus, you conclude that the bag that held the most vibrant beads is the bag with no sunscreen.
Remember that the temperature is a measure of the kinetic energy:. The relation is: the higher the temperature the higher the kinetic energy.
Therefore, the more the particles vibrate, the higher the kinetic energy and the higher the temperature.
