The same number as in an atom of Ca, the same as the atomic number of Ca. An ion will have a different number of electrons than protons, so it is not 20. Only neutral atoms have the same number of electrons as protons, which is the same as the atomic number. A calcium ion (Ca+2) has two less electrons than protons (having lost two to fulfill the octet rule), so it has 18 electrons.

How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
A positive two ion of calcium Ca would have how many protons electrons and neutrons?
A positive calcium ion (Ca^2+) has 20 protons, 18 electrons, and 20 neutrons. This is because the atomic number of calcium is 20, indicating 20 protons in a neutral atom, and losing 2 electrons makes it positively charged while the number of protons and neutrons remains the same.
What charge does an ion have if it has more protons then electrons?
The ion would have a positive charge if it has more protons than electrons. Since protons have a positive charge and electrons have a negative charge, an excess of protons will result in an overall positive charge for the ion.
What charge does an ion have if it has more protons than electrons?
A net postive charge
How many protons does calcium-39 have?
The number of protons in an element will be the same regardless of the isotope or ion. To have a different number of protons would change what type of element it is. So, it is not necessary to say "how many protons does calcium-41 have?" because it is the same as saying "how many protons does calcium have?" The answer is the same in any case, the same as the atomic number, 20.
How many protons neutrons and electrons will positive two ion of calcium have?
A positive two ion of calcium will have 20 protons, 18 neutrons, and 18 electrons. The number of protons and neutrons in a calcium ion remains the same as in a neutral calcium atom (calcium has 20 protons and about 20 neutrons in its nucleus), but it loses two electrons to become positively charged.
How many protons electrons and neutrons does a positive two ion for calcium?
20 p+ 20 n
A positive two ion of calcium Ca would have how many protons electrons and neutrons?
A positive calcium ion (Ca^2+) has 20 protons, 18 electrons, and 20 neutrons. This is because the atomic number of calcium is 20, indicating 20 protons in a neutral atom, and losing 2 electrons makes it positively charged while the number of protons and neutrons remains the same.
How many protons and electrons does calcium ion have?
20
How many protons neutrons and electrons does calcium ion have?
20
What charge does an ion have if it has more protons then electrons?
The ion would have a positive charge if it has more protons than electrons. Since protons have a positive charge and electrons have a negative charge, an excess of protons will result in an overall positive charge for the ion.
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.
What is the positive and negative ion for calcium oxide?
The positive ion in calcium oxide is the calcium ion (Ca^2+), which has lost two electrons. The negative ion in calcium oxide is the oxide ion (O^2-), which has gained two electrons.
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)
What charge does an ion have if it has more protons than electrons?
A net postive charge
How many protons does calcium-39 have?
The number of protons in an element will be the same regardless of the isotope or ion. To have a different number of protons would change what type of element it is. So, it is not necessary to say "how many protons does calcium-41 have?" because it is the same as saying "how many protons does calcium have?" The answer is the same in any case, the same as the atomic number, 20.
How many protons does an atom of Calcium have in its nucleus?
A calcium ion has 20 protons, the same as its atomic number. The number of electrons depends on the charge on the ion. For the most common calcium ion with a charge of +2, the number of electrons is 18; 20 - 18 = +2. The number of neutrons depends on the isotope that is ionized and is equal to the mass number of the isotope minus the atomic number of 20.
