honest the subject is since so it's not biology i think but plz help it is worth 50 pts

nitrogen , CALCIUM , nitrogen , Carbon-14 , Mercury , Boron

Explanation:

A. nitrogen

The atomic number of nitrogen is 7. How many protons, neutrons, and electrons make up an atom of nitrogen-15? Socratic.

B. CALCIUM

 CALCIUM - I have 20 neutrons and am found in your teeth and bones

C. nitrogen

The atomic number of nitrogen is 7. How many protons, neutrons, and electrons make up an atom of nitrogen-15? Socratic.

D. Carbon-14

Carbon-14 atoms have two extra neutrons, giving them a total of 8 neutrons. Carbon-14 has an atomic mass of 14 ( = 6 protons + 8 neutrons).

E. Mercury

Mercury is a chemical element with symbol Hg and atomic number 80.

F. Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).

uh two lol

the real answer is b. scintillation counter
