Question

this is a bohr model of an atom or ion. select the nuclear notation that represents this atom or ion. refer to a periodic table. ₁₄⁷si ₇¹⁴n ₁₄⁷n ₇¹⁴si

Explanation:

Step1: Count protons

Count the number of yellow - colored particles (protons) in the nucleus. There are 7 protons.

Step2: Determine atomic number

The atomic number (Z) is equal to the number of protons. So, Z = 7. The element with atomic number 7 is nitrogen (N).

Step3: Count protons and neutrons

Count the total number of particles (protons + neutrons) in the nucleus. There are 7 protons and 7 neutrons, so the mass number (A) = 7+7 = 14.

Step4: Write nuclear notation

The nuclear notation is written as $^{A}_{Z}X$, where A is the mass number, Z is the atomic number and X is the chemical symbol of the element. So the nuclear notation for this atom is $^{14}_{7}N$.

Answer:

$^{14}_{7}N$
