What is the symbol for an ion with 63 protons, 60 electrons, and 88 neutrons?
If an ion contains 50 protons, 68 neutrons, and 48 electrons, what is its symbol?
Please help me.. im soo lost in this problem!
The atomic number is 63. Look up the element for 63. It's on the periodic table.
The number of protons + the number of neutrons is the mass number. Since an atom is neutral, 63+ charges(protons) but only 60 negative charges (electrons), that means the ion has a charge of +3 (63+ - 60- = 3+).
Element 63 is Europium, symbol Eu.
On the left of the symbol write 63 has a subscript. On the left of the symbol write 151 as a superscript. (That's 63 protons + 88 neutrons = 151 total = mass number). On the right of the symbol, write as a superscript 3+ to show the charge. It should look approximately like this:
15163Eu3+
Now you should be able to do the second one. I shall be happy to check your work.
Note in the above that the 151 and the 63 should be directly above and below each other.
Total mass number(50+68=118)
+2 charge (50-48=2)
50 protons
Sn
Oh, don't worry, I'm here to clown around and help you out! Let's tackle these puzzles one at a time.
For the first ion with 63 protons, 60 electrons, and 88 neutrons, the symbol can be determined by looking at the element with 63 protons on the periodic table. That element happens to be europium! So, the symbol would be Eu.
Now, moving on to the second ion with 50 protons, 68 neutrons, and 48 electrons. We need to find the element with 50 protons, which turns out to be tin. So, the symbol would be Sn.
Hope that clears things up for you! If you have any more questions or need more laughs, feel free to ask!
Don't worry, I can help you with these problems!
To determine the symbol for an ion, you need to know the element it belongs to and decide whether it is a cation (positive charge) or an anion (negative charge).
In the first problem, the ion has 63 protons and 60 electrons. Since the number of protons determines the element, we look for the element that has 63 protons. This corresponds to the element with atomic number 63, which is europium (Eu) on the periodic table.
To determine the symbol of the ion, we need to know whether it is a cation or an anion. If an ion has more protons than electrons, it is a cation and has a positive charge. In this case, if the ion has 60 electrons, which is 3 less than the number of protons, it means that 3 electrons have been lost. Therefore, the symbol for this ion is Eu3+.
In the second problem, the ion has 50 protons and 48 electrons. Again, we need to find the element with 50 protons on the periodic table. This corresponds to the element with atomic number 50, which is tin (Sn).
To determine the symbol, we need to know the charge of the ion. Since the ion has fewer electrons than protons, it means that some electrons have been lost, resulting in a positive charge. In this case, 2 electrons have been lost since there are 48 electrons. Therefore, the symbol for this ion is Sn2+.
