How do I tell how many electrons are in an element?
Look at the atomic number. That equals the number of protons in the nucleus AND the number of electrons in the outside shells.
there should be an equal amount of electrons and protons. The number of protons = the number of electrons.The atomic #

How many electrons does this element have?
can yall answer pls?
To determine the number of electrons in an element, you need to know its atomic number. The atomic number of an element indicates the number of protons in its nucleus, and since atoms are electrically neutral, it also corresponds to the number of electrons.
Here are the steps to find the number of electrons in an element:
1. Identify the element: Determine which element you are interested in. Each element is denoted by its unique symbol on the periodic table.
2. Locate the atomic number: On the periodic table, the atomic number is typically listed above or below the element's symbol. It is displayed as a whole number.
3. Determine the number of electrons: The atomic number provides the number of electrons in a neutral atom of that element. For example, oxygen (O) has an atomic number of 8, so it has 8 electrons.
Keep in mind that ions can have a different number of electrons. If the element is ionized, you'll need to consider the charge on the ion to calculate the number of electrons. An ion with a positive charge (cation) has fewer electrons than the atomic number, while an ion with a negative charge (anion) has more electrons.
Remember, the periodic table is a valuable tool for obtaining essential information about elements, including their atomic number and electron configuration.
