Answer:
A.) a proton is gained
Explanation:
A.) is correct. Protons are located in an atom's nucleus. As you travel to the right on a period, the elements are gaining more protons. For instance, magnesium, which is one space to the right of sodium, has one more proton than sodium.
B.) is incorrect. Like protons, as you travel to the right across a period, each element gains another electron. However, while the statement itself is true, <u>electrons are not located in an atom's nucleus</u>.
C.) is incorrect. Like protons, as you go across a period, the number of <u>neutrons in the nucleus increases</u>, not decreases.
D.) is incorrect. As noted in B.), the number of electrons in each element increases across the period. Therefore, as more electrons surround the nucleus, the <u>electron cloud size increases</u>.
49 neutrons in each nucleus.
<h3>Explanation</h3>
For each nucleus:
Mass number = Number of protons + Number of neutrons.
The atomic number of a nucleus is the same as its number of protons. The atomic number of the nucleus here is 31. There are 31 protons in each nucleus.
- Mass number = 80;
- Number of protons = Atomic number = 31;
- The number of neutrons is to be found.
Again,
Mass number = Number of protons + Number of neutrons.
80 = 31 + Number of neutrons.
Number of neutrons = 80 - 31 = 49.
A 3.0 L balloon is 2.5 times as big as a 1.2L balloon, and 3 times .060 equals .18, so if you multiply .18 by 2.5 you get .45 moles of air i’m pretty sure
