Identify the monoatomic ion that has the following properties.
a. 11 protons and 10 total electrons
Na+
b. 9 protons and 8 valence electrons
F-
c. 47 protons and 46 total electrons
Ag+
d. 28 protons and 26 total electrons
Ni2+
All look ok except for b.
9+ and 8- gives F+
9 protons and 9 electrons = Fo which we write as F2.
9 protons and 10 electrons = F^-
50 protons 68 neutrons and 46 electrons
To identify the monoatomic ion that has the given properties, we need to consider the information provided about the number of protons and total electrons.
a. 11 protons and 10 total electrons:
To determine the monoatomic ion for this case, we need to find the element that has 11 protons and then determine the charge on the ion. The element with 11 protons is sodium (Na), and since it has one more electron (10 electrons) than protons, it gains a positive charge. Therefore, the monoatomic ion is Na+.
b. 9 protons and 8 valence electrons:
To identify the monoatomic ion for this case, we need to find the element with 9 protons and determine the charge on the ion. The element with 9 protons is fluorine (F), and since it has one more electron (8 valence electrons) than protons, it gains a negative charge. Therefore, the monoatomic ion is F-.
c. 47 protons and 46 total electrons:
To determine the monoatomic ion for this case, we need to find the element with 47 protons and determine the charge on the ion. The element with 47 protons is silver (Ag), and since it has one less electron (46 total electrons) than protons, it gains a positive charge. Therefore, the monoatomic ion is Ag+.
d. 28 protons and 26 total electrons:
To identify the monoatomic ion for this case, we need to find the element with 28 protons and determine the charge on the ion. The element with 28 protons is nickel (Ni), and since it has two less electrons (26 total electrons) than protons, it gains a positive charge of 2. Therefore, the monoatomic ion is Ni2+.
