look at the Periodic Table of elements.
You want an Ion, which is why it has a different number of protons than electrons.
It's atomic number must either be 3 or 2, right? those are the only numbers you have. So it must either be lithium or helium. So the question is,
When an atom becomes an ion, does it lose an electron or gain a proton? If it loses the electron, it must be lithium, but if it gains a proton, it must be helium.
good luck
What else can I help you with?
What is the chemical symbol for an ion with 29 protons and 27 electrons?
The chemical symbol is Cu2+.
What is the chemical symbol for the ion with 33 protons and 36 electrons?
The symbol for this ion is As3-. The charge is 3- because there are three more electrons than protons.
What is the chemical symbol for the ion with 17 protons and 18 electrons?
Cl-
What is the chemical symbol for the ion with 28 protons and 30 elcetrons?
According to the periodic table the ion with 28 protons and 30 electrons, the chemical sybol is Ni-58
What is the chemical symbol for ion with 31 protons 39 neutrons and 28 electrons?
The chemical symbol for an ion with 31 protons, 39 neutrons, and 28 electrons is ^70Ga3+. This represents gallium with a charge of +3 due to the loss of 3 electrons.
If An ion has 8 protons 9 neutrons and 10 electrons the symbol for the ion is?
The symbol for the ion with 8 protons, 9 neutrons, and 10 electrons is ^17O.
What is the symbol of an ion with 50 protons 68 neutrons and 48 electrons?
The symbol of an ion is determined by the number of protons and electrons. With 50 protons and 48 electrons, this ion has a +2 charge (50 protons - 48 electrons = +2 charge). Therefore, the symbol would be written as Sn2+.
What the chemical symbol for the ion with 12 protons and 10 electrons?
Magnesium, with a +2 charge.
What is the symbol for the ion with 22 protons and 24 electrons?
Ti2- would be the symbol for an ion with 22 protons and 24 electrons. This would be EXTREMELY unlikely to exist though. Ti2+ is more usual with 22 protons and 20 electrons. Ti4+ is even more stable with 22 protons and 18 electrons.
What is the chemical symbol for the ion with 73 protons 108 neutrons and 68 electrons?
The atomic number is determined by the number of protons, so the base element is tungsten. The net charge is the number of protons minus the number of electrons, so the overall symbol is W with a 6+ superscript.
Write the chemical symbol for the ion with 95 protons and 89 electrons?
the number of protons stay the same in every element (i think). So the number of protons is the atomic number. Therefore, this is tungsten (W). The electrons and nuetrons are the only thing that change.
What is the chemical for the ion with 29 protons and 27 electrons?
It would end up answering with Cobalt = Co. Because the protons stay the same and add the protons and electrons together equaling 59. So (Co+2) would be the final answer.
