2. Why would a calcium (Ca) atom be larger than a bromine (Br) atom even

Chemistry
1 answer:
Wittaler [7]3 years ago
3 0

Within a period, the atom size decreases with increasing group number (from left to right), since the nuclear charge and the number of external electrons increase within the period, but the number of shells does not. The electrons are more strongly attracted to the nucleus and are therefore closer to the nucleus.

4) In the experiment, why do you think they started with water that was the same temp (118 °F) for each
kondor19780726 [428]

Answer:

4. I think that they started with water that was the same tsmpurature because if they didnt start with the same temp of water then it would be harder to tell which one was better. and could hold the most heat.

5. yes i think it would matter, because if you have more water in one cup it might stay warmer than it would with the cups with less water, and if it was thicker it would hold mor heat because it is not so thin that the heat is just gonna come out it has to come through more for the heat to get out.

Explanation:

sorry if these are to long but thats how i would answer them.

hope it helped
