Question

an ion from a given element has 29 protons and 27 electrons. what is the symbol for the ion? what is the name of the element? what is the charge on the ion?

Explanation:

Step1: Identify the element

The number of protons determines the element. With 29 protons, the element is copper (Cu).

Step2: Calculate the charge

Charge = Number of protons - Number of electrons. Given 29 protons and 27 electrons, Charge = 29 - 27 = + 2.

Step3: Write the ion - symbol

The ion symbol is written as the element symbol followed by the charge as a superscript. So the ion symbol is $Cu^{2 + }$.

Answer:

Name of the element: Copper
Charge on the ion: + 2
Symbol for the ion: $Cu^{2 + }$
