Naturally occurring zinc (Zn) is composed of the 5 stable isotopes 64Zn, 66Zn, 67Zn, 68Zn, and 70Zn with 64Zn being the most abundant (48.6% natural abundance). Twenty-one radioisotopes have been characterised with the most abundant and stable being 65Zn with a half-life of 244.26 days, and 72Zn with a half-life of 46.5 hours. All of the remaining radioactive isotopes have half-lives that are less than 14 hours and the majority of these have half lives that are less than 1 second.
Zinc is a metal, all metals are positively charged, any element positively charged is or acts like a cation (pronounced cat-eye-on), therefore zinc is a cation.

How many protons does zinc (zn) have?
Zinc has 30 protons.
Why does ZnOH2 Dissolve in excess OH?
The formation of the soluble Zn(OH)4- ion (tetrahydroxidozincate ion)
What is the most common isotope of uranium?
The most common isotope of zinc is the one with mass number 64; the atomic number of zinc is 30, which means each zinc nucleus contains 30 protons, and the mass number is defined as the sum of the numbers of neutrons and protons. Therefore, the number of neutrons is (64 - 30) or 34.
Atomic number of 30 and 34?
The atomic number of an element is the number of protons in an atom's nucleus. Element with an atomic number 30 is Zinc (Zn), while element with an atomic number 34 is Selenium (Se).
What would an atom Zn become if it gained a proton?
If an atom of zinc (Zn) gained a proton, it would become a different element altogether due to the change in the number of protons. Since the number of protons determines the element's identity, adding a proton would change its atomic number and transform it into a new element.
What is the ion that has 30 protons and 28 electrons?
The number of protons = atomic numberThe number of electrons = atomic number - net ion charge (no charge means not ion)The number of neutrons = mass number - atomic numberAlways start with protons if they are given. If they are not given, use the other numbers to figure out how many protons there are. The 9 protons in this question immediately tell you that the atomic number is 9. This is a dead giveaway as to which element is being discussed. Just look on the periodic table for the atomic number of 9, which is... Flourine! The number of electrons will tell you whether this is an ion or not. Ions are not stable (neutral). This means that they have a negative or positive charge. If you know how to draw a shell diagram, you can place the electrons. If all shells are filled completely and there are no extra electrons in unfilled outer shell, then it is not an ion.
What is the oxidation number of Zn(OH)4 -2?
The oxidation number of Zn in the complex ion Zn(OH)4 2- is +2. This is because the overall charge of the complex ion is -2, and each hydroxide ion (OH-) has a -1 charge. Hence, the zinc (Zn) ion must have a +2 charge to balance the overall charge of the complex ion.
How many protons does zinc (zn) have?
Zinc has 30 protons.
How many elctron in zinc?
Zinc is a bluish metallic element with the symbol of Zn. Its atomic number 30. It also has 30 protons and electrons.
How many protons electrons and neutrons are in the formula zinc and chlorine?
Zinc chloride has the chemical formula ZnCl2.The total number of protons is 64; the total number of electrons is also 64.The number of neutrons depends on the isotopes of Zn and Cl.
How many protons does Zn positive 2 charge have?
Zinc (Zn) typically has 30 protons in its nucleus. However, with a positive 2 charge, it has lost two electrons, leaving it with a net charge of +2. This does not change the number of protons, which remains at 30.
How many protons and electrons are in the element Zinc2 plus?
ZnCl2 is not a element. It is an compound. however Zn contains 30 protons.
What is the chemical for the ion with 29 protons and 27 electrons?
The chemical element with 29 protons is copper. When it has 27 electrons it forms the ion Cu2+ with a 2+ charge.
How many neutrons are there in a zinc Zn atom with a mass number of 66?
A zinc atom with a mass number of 66 has 34 neutrons. This is determined by subtracting the atomic number (number of protons) from the mass number, since the mass number represents the sum of protons and neutrons.
Neutral atom with 30 protons and 34 neutrons what is atomic number?
The atomic number is 30 because it is determined by the number of protons in the nucleus of an atom. Since the atom is neutral, it will also have 30 electrons surrounding the nucleus to balance the positive charge of the protons.
Is ZnOH2 an acid?
Zn(OH)2 is actually a base as it contains the hydroxide ion (OH-) which can accept protons and increase the pH of a solution.
Why is the oxidation number of zinc 2 plus?
The oxidation number of zinc in Zn^{2+} is +2 because zinc typically loses two electrons to attain a full outer electron shell in its compounds.
