Question
Part A The innermost electron shell of an atom can hold up to ele ctrons. 0 18 e 32 2 Submit Part B Which of these relationships is true of an uncharged atom? The atomic mass is equal to the number of electrons. The number of neutrons is equal to the number of protons The atomic mass is equal to the atomic number The number of protons is equal to the number of electrons The number of electrons is equal to the number of neutrons. Submit Part C What determines the types of chemical reactions that an atom participates in?Explanation / Answer
A) The correct option is 2.
The innermost electron shell of an atom can hold up to 2 electrons. Two electrons in the first shell, then it upgrades to 8.
B) The correct option The number of protons is equal to the number of electrons.
The number of positive charges is equal to the number of negative charges.
C) The correct option is the number of electrons in the outermost electron shell.
An atom is least likely to participate in a reaction when its outermost shell is stable.
