Question

Sodium is an element found in table salt. It contains 11 protons and

12 neutrons. How many electrons are found in a neutral atom of
sodium?
A. 11
C. 23
B. 12
D. 1

Answer 1

11 electrons are found in a neutral atom of sodium.

Step-by-step explanation:

atoms are made up electrons and protons. Electrons are negatively charged particles and protons are positively charged particles. The number of electrons and protons are constant or fixed in an element. However, the number of electrons and protons may not be always equal. the number of protons in the atom is equal to the atomic number of the element. sodium's atomic number is 11 and thus the number of protons is also equal to 11. since sodium atom is neutral, the number of protons = the number of electrons. thus the number of electrons in a neutral sodium atom is 11
