Isotopes of the same element always have the same atomic number because the atomic number is like the identity of each element and if it is changed the element is changed for example isotopes of Carbon are: ₆C¹² , ₆C¹³ and ₆C¹⁴ and if we change the atomic number form 6 to 7 we will have Nitrogen element ₇N¹⁴
So the correct answer is Z- number (atomic number)

Answer:
A star begins its life as a cloud of dust and gas (mainly hydrogen) known as a nebula. A protostar is formed when gravity causes the dust and gas of a nebula to clump together in a process called accretion. ... If a critical temperature in the core of a protostar is reached, then nuclear fusion begins and a star is born.

Fluorine is an element with the highest electronegativity value.
Answer: im pretty sure its the last (one daughter cell has no similarity to its parent cell.)
Explanation: bc a daughter cell has 30 and the parent cell would have 46 and thats not twice or half as many and they arent the same either so the last one makes sences
