The atomic number of
zinc
is 30, which means the number of protons is 30 and the number of electrons is 30. So ion of zinc with 28 electrons has ionic charge 2+.
What is the ionic charge for an atom that has 30 protons and 28 electrons?
What symbol designates an ion that contains 30 protons and 28 electrons? 30 + (-28) =
+2
.
What element has 30 protons 28 electrons?
#30 –
Zinc
– Zn.
What ion has 28 electrons?
FREE Expert Solution
We’re being asked which among the given ions has twenty-eight (28) electrons. Therefore, the ion that has 28 electrons is
Zn
2 +
.
Does Zn have 28 electrons?
The
Zn2
+ ion has lost two electrons, which leaves it with 30 protons and 28 electrons. The electron configuration of Zn2+ is 1s22s22p63s23p63d10 .
Why does zinc have 30 protons?
Explanation: The number of protons, i.e. positively charged nuclear particles, gives the identity of the
element
. Here Z = 30 ; therefore, the element is zinc. There are 26 neutral nuclear particles, so we have 56Zn .
What has 8 protons and 10 neutrons?
Because protons and neutrons are roughly equal in mass, an isotope’s number is equal to the sum of its protons and neutrons. Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and
oxygen 18
has 8 protons and 10 neutrons.
What is the proton symbol?
| Particle Symbol Location | proton p + inside the nucleus | electron e − outside the nucleus | neutron n 0 inside the nucleus |
|---|
How many protons and electrons are in Fe3+?
Difference of number of electrons from number of protons defines the charge on an atom. For example, among atoms of iron, all with 26 protons, Fe2+ has 24 electrons and Fe3+ has
23 electrons
, whereas elemental (uncharged) Fe has 26 electrons. the mass of an atom is outside the nucleus.
What is the charge of 25 electrons?
Protons are the only charged particle in the nucleus. However, the overall charge of the atom is
zero
. That’s because protons in the nucleus and electrons outside the nucleus have opposite charges and the sum of +25 and -25 is zero.
What element has 28 electrons and a charge of 2+?
#28 –
Nickel – Ni
.
What is the symbol for the ion with 30 protons and 28 electrons?
The atomic number of zinc is 30, which means the number of protons is 30 and the number of electrons is 30. So ion of zinc with 28 electrons has ionic charge 2
+
.
Which of these represents an atom with 8 protons and 10 electrons?
An oxygen ion
has 8 protons and 10 electrons. The number of protons tells us the identity of the element because the number of protons is the same as…
What is the correct electron configuration for Zn 2+?
The Zn
2 +
ion has lost two electrons, which leaves it with 30 protons and 28 electrons. The electron configuration of Zn

Why is zinc ion 2+?
The chemistry of zinc is almost entirely governed by its +2 ion charge. A Zn
2 +
cation
has shed the two electrons in its 4s subshell
, leaving only the filled 3d subshell.
