Question

below is a model of a portion of the periodic table of elements. this portion illustrates a single element. gather and record information about the element using the model. how many protons does this element have? __ how many electrons does this element have? what is the atomic number of this element? what is the chemical symbol of this element? what is the name of this element? what is the atomic mass of this element? how many neutrons does this element have? __ n nitrogen 14.007

Explanation:

Step1: Recall atomic number property

The atomic number is equal to the number of protons. For nitrogen (N), the atomic number is 7, so the number of protons is 7.

Step2: Recall electron - proton relationship

In a neutral atom, the number of electrons is equal to the number of protons. So nitrogen has 7 electrons.

Step3: Identify atomic number

The atomic number of nitrogen is 7.

Step4: Identify chemical symbol

The chemical symbol is given as N.

Step5: Identify element name

The name of the element is nitrogen.

Step6: Identify atomic mass

The atomic mass is 14.007.

Step7: Calculate number of neutrons

The number of neutrons = atomic mass (rounded to the nearest whole number) - number of protons. Rounding 14.007 to 14, and since protons = 7, neutrons = 14 - 7=7.
