Does a chloride ion have more protons than electrons?
Yes. The charge of a cation tells how many more protons than electrons it has. For example Fe3+ has three more protons than electrons. However these protons were not gained, since an element always has the same number of protons no matter what its charge is. So in order for an element to have more protons than electrons it has to lose the electrons.
What is the electrical charge of the chlorine ion?
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
If a calcium atom has 20 protons and 20 neutrons and 18 electrons what is the magnitude of it's charge in coloumbs?
The charge of a calcium atom with 18 electrons will be +2 elementary charges since it has 20 protons and 18 electrons, resulting in a net positive charge. Each elementary charge is approximately 1.602 x 10^-19 Coulombs, so the total charge of the calcium atom would be 2 * 1.602 x 10^-19 Coulombs.
If calcium has a 2 charge and oxygen has a -2 charge what is the chemical formula?
CaO. The charges of the and the cation (the positive element, Ca) and the anion (the negative element, O) must add up to zero.
A positive two ion of calcium ca plus 2 would have how many protons electrons and neutrons?
A calcium ion with a charge of +2 has lost 2 electrons, resulting in an electron count of 18. Since calcium has an atomic number of 20, the number of protons remains at 20. To find the number of neutrons, subtract the number of protons (20) from the mass number (which can be found on the periodic table), which for calcium is 40, to get 20 neutrons.
Does a chloride ion have more protons than electrons?
Yes. The charge of a cation tells how many more protons than electrons it has. For example Fe3+ has three more protons than electrons.

So in order for an element to have more protons than electrons it has to lose the electrons.
What is in the nucleus of the element calcium?
Calcium (Ca) contains: 20 protons (positively charged) 20 neutrons (neutral) Outside of the nucleus: 20 electrons (negative charge) with the configuration 2-8-8-2 Calcium has an atomic mass of 40.08
How many protons and does ca plus 2 have?
The number of protons in an element does not depend on the charge of the element. An atom of a given element has the same number of protons as an isotope of that element. Thus, a calcium ion has 20 protons, just like atoms in calcium metal.
How many protons electrons and neutrons in calcium-44?
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
Did Ca plus plus gain an electron to produce the charge?
Ca2+ is positively charged. Remember that an electron is a particle with negative charge; therefore, the element Calcium (Ca) has LOST 2 electrons in order to be positive 2.
Why proton is positively charged?
I am going to borrow heavily from the answer to "Why do electrons have a negative charge?" Protons have a positive charge because the charge is part of what the particle is made of. If it were possible to remove the positive charge from the proton we would then have a neutron.
What is the correct formula for calcium dihydogen phosphate?
This formula is Ca(H2PO4)2. Since a dihydrogen phosphate anion has only one negative electric charge and a calcium cation has a positive charge of two, twice as many of the anions are required.
What is the electrical charge of the chlorine ion?
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
How many electrons does ci have?
A neutral chlorine atom (Cl) has 17 electrons. Each electron has a negative charge, and the total number of protons in the nucleus (which is also 17 in the case of chlorine) balances the negative charge of the electrons to keep the atom overall neutral.
How many neutrons does the isotope Ca have?
42 total mass -20 protons = 22 neutrons
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
What is the symbol and charge for calcium?
The symbol for calcium is Ca. Calcium atoms are neutral because they have 20 protons and 20 electrons. However when calcium atoms lose their 2 outershell electrons, it becomes a positively charged ion-Ca2+.
