Question

for mg 2+ with 13 neutrons what is the isotope name *
magnesium-12
magnesium-26
magnesium-24
magnesium-25
magnesium-13
magnesium-11
for mg 2+ with 13 neutrons what is the number of electrons *
131
12
53
44
22

Explanation:

Step1: Recall magnesium's atomic number

Magnesium (Mg) has an atomic number of 12, which means it has 12 protons.

Step2: Calculate mass - number for isotope name

The mass - number of an isotope is the sum of protons and neutrons. Given 12 protons and 13 neutrons, mass - number = 12 + 13=25. So the isotope name is Magnesium - 25.

Step3: Determine number of electrons for Mg 2+

A neutral magnesium atom has 12 electrons. Since Mg 2+ has a 2+ charge, it has lost 2 electrons. So the number of electrons is 12 - 2 = 10. But there is no 10 in the options for the electron - number question, which might be an error in the options provided. For the isotope name, based on our calculation, the correct answer is Magnesium - 25.

Answer:

For the isotope name question: Magnesium - 25
For the number of electrons question: No correct option among given ones (should be 10)
