Answer:
Explanation:
In the first nucleus we are told that there are two protons and one neutron. Let us remember that the mass number = number of protons + number of neutrons.
This implies that, for the first specie the mass number is 3, for the second specie the mass number is 6 and the third specie has a mass number of 7 and so on. The mass number is indicated as a superscript.
The atomic number is the number of protons in the nucleus of the atom and helps us to identify the atom. It is always written as a subscript as shown.
Answer:
<span>D. Remove electrons from its full outer energy level
</span>
Explanation:
The atom achieves its stable state when its outermost shell is completely full with 8 electrons (based on the octet rule)
Any atom whose outer shell is not completely full tends to lose gain or share electrons in order to complete this shell and become stable
Therefore, it is pointless for an atom with an outer shell having 8 electrons to lose electrons, because by this it convert from being stable to being unstable.

Answer:
Q Line A
A: (a) 0 (b) 20
B: (b) 10 (c) 10
C: (c) 10 (d) 10
D: (d) 10 (e) 13
E: (e) 13 (f) 0
F: (f) 0 (g) 0
a: The velocity is whatever you need to see when you are specifically using a numberline so the answer for a is just 10
b: The velocity for this one is not as easy as the last one, its 7.
Explanation:
When you have a number line and your trying to find a numberline, you just have to subtract the smaller line to the largest number but if you are trying to find the velocity in beetween more than one thane you add the two biggest ones and subtract the smallest one and if you make a wrong move like add the biggest and smalles youll... still get the same answer so it doesnt matter really but its just easier to do the smallest one as the subtracting number just FYI. Happy spring break!
