Question

nitrogen 14.007 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? 2 below is a different model of a portion of the periodic table of elements. this portion also illustrates a single element. gather and record information about this element. carbon 6 c 12.011 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?

Explanation:

Step1: Identify element - Nitrogen

Atomic number is number of protons. Chemical symbol is N, name is Nitrogen, atomic mass is 14.007. Neutrons = Atomic mass (rounded) - Atomic number. Atomic number of N is 7. Rounding 14.007 to 14, neutrons = 14 - 7 = 7.

Step2: Identify element - Carbon

Atomic number = number of protons = number of electrons (for neutral atom). Chemical symbol is C, name is Carbon, atomic mass is 12.011. Atomic number is 6, so protons = 6, electrons = 6. Neutrons = Atomic mass (rounded) - Atomic number. Rounding 12.011 to 12, neutrons = 12 - 6 = 6.

Answer:

Nitrogen:
