What is the correct identity of an element that contains 50 electrons and 69 neutrons?

As asked, there is not enough information in your question to answer it as there are no "following" from which the choice of "Which of the following is the correct identity..." can be made.
However, from the given information:
Elements are electrically neutral, so if it has 50 electrons, it must also have 50 protons; and the number of protons gives the atomic number of the element - the element with atomic number 50 is Tin (Sn).
The number of neutrons can vary which isotope it is (eg Deuterium is Hydrogen with 1 neutron, Tritium is Hydrogen with 2 neutrons).
The number of neutrons and protons together in the nucleus gives the relative atomic weight of the element; tin has a relative atomic weight of 119 which less the 50 protons leaves 69 neutrons, confirming the element.
Now you know the element, you can choose "which of the following" (which were not included in your question) is the right answer; or even better, re-write your question to something like "which element has 50 electrons and 69 protons" as opposed to copying your teacher's question (and possibly committing copyright infringement, aka piracy).

How many leaters in one ceusic?
Correct Question: How many litres are there in one cusec? Answer: A cusec (ceusic, cusic) contains a fluid flow of 28.314 litres per second.
See you after an hour and a few minutes is a correct grammar?
No, it is correct grammar, not a correct grammar.
When 2610 11.7 0.22 are added the answer to the correct number of decimal places is?
The correct answer depends on what is known about the number 2610. If it is known to be correct to 3 significant figures, the correct answer is 2620. If it is known to be correct to 4 significant figures, the correct answer is 2622. If all the numbers are known to be accurate to at least 2 decimal places then the correct answer is 2621.92
Which one is correct- 1. Vacation 2. Vacations?
""'Vacation'"" is correct ....................... =========================== Both are correct. "Vacations" is plural.
What is 1.086 correct to 1 decimal place?
The correct answer is 1.1
Is it correct that nucleus contains electrons and protons?
The atomic nucleus contain neutrons and protons.
What is the correct number of protons electrons and neutrons in the isotope 36Cl respectively?
Protons = 17; Electrons = 17; Neutrons = 19
Do neutrons carry no charge?
Correct. Protons are positive, electrons are negstive, and neutrons have no charge
Do protons have positive charge neutrons have negative charge and electrons have no charge?
No, protons have positive charge, electrons have negative charge and neutrons have no charge
Are electrons smaller then protons and neutrons?
In their mass, that is about correct. The volume can not be accurately determined.
What compose a molecule?
"Atoms" is probably the answer sought, although protons, electrons, and usually neutrons would also be correct.
How many protons neutrons and electrons are in gadolinium?
Proton: 64 Electron: 64 Neutron: 93 if my math is correct
What an atom is made of?
The correct grammar is 'What is an atom made of?', and the answer is that the nucleus is surrounded by Neutrons (no charge) and Protons (positive charge), and outside the nucleus are outer rings with Electrons (negative charge) on them. The amount of subparticles depends on the atom.
What is the correct number of protons neutrons and electrons for a neutral atom of sulfur?
The number of protons and of electrons is always 16, which is the atomic number of sulfur. The number of neutrons depends on which isotope of sulfur is the atom considered, but since the most common isotope is sulfur-32, the number of neutrons is most commonly also 16.
Is the current model of the atom a theory or a fact?
The fact is that the simple model of a nucleus containing neutrons and protons surrounded by electrons is correct.
An atom contains 55 protons and 78 neutrons. Which nuclide symbol is the correct symbol for the atom?
133/55 Cs
The atomic mass of an atom is 46 and it has 22 neutrons. How many electrons does it have?
46. That answer is incorrect. If the atom has 22 neutrons, then it must have 24 protons to make up the total mass of 46. A neutral atom always has the same number of electrons as protons so the correct answer is 24.
