What is the ion notation for an atom with 6 protons and 2 electrons?
we can write the name of element anthen write 4+ as superscript
If an atom has 49 protons how many electrons does it have?
A neutral atom with 49 electrons will have 49 protons. The number of protons and electrons are always the same in a neutral atom. If the number of protons is not matched by the number of electrons, then the atom is charged and is called an ion. Further, if protons outnumber electrons, the atom is positively charged and is a positive ion. For situations where electrons outnumber protons, the opposite is true. The element with 49 protons in it is indium, by the way.
Is an atom with 12 protons 12 electrons and 12 neutrons an ion?
No. The number of protons and electrons is the same, resulting in a neutral atom (magnesium in this case). In order to be an ion the number of protons and electrons must be different.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
How do sodium atom and a positive sodium ion differ?
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
What is the ion notation for an atom with 6 protons and 4 electrons?
C2+
When is an atom called ion?
An ion is a electrically charged atom (negative ion) has more electrons that protons and positive ion has more protons that electrons)
When an atom has more electrons than protons it is?
An atom with more protons than electrons is a cation.
If an atom has lost more protons than electrons it is called a ion?
If the atom has more electrons than protons, then yes it is an ion.
When an atom has more electrons that protons it is?
An anion is an ion with more electrons than protons.
Select the answer that correctly indicates the number of protons and electrons for this atom or ion Sulfide ion?

What can be said about the number of protons and electrons in an atom Why?
For any element an atom contains EQUAL number of protons and electrons. An atom has no charge. If any given atom has an unequal number of electrons and protons it is no longer an atom, but an ION.
