How many protons neutrons and electrons are in calcium?
Calcium is the 20th element, with 20 protons. Since a stable atom has a net charge of 0, we must have 20 electrons. The number of neutrons will be the same as the number of protons: it is also 20.
How many protons and neutrons are in the nucleus of calcium?
Atomic Structure of Calcium There are 20 protons and 20 neutrons in the nucleus.
What element has 18 protons and 22 neutrons?
Argon So, the atomic number is also (18), and the element with atomic number (18) is Argon with the symbol (Ar). Now we need to find the mass number of Argon. Since, a neutral atom of argon also has 22 Neutrons. So, it is clear that this is not an isotope but a neutral atom of Argon.
What has 32 protons and 38 neutrons?
Germanium-70 is composed of 32 protons, 38 neutrons, and 32 electrons.
What has 16 protons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.
What has 17 protons and 18 neutrons?
Answer and Explanation: Chlorine-35 has 17 protons and 18 neutrons.
What has 32 protons and 33 electrons?
Germanium | Ge (Element) – PubChem.
What has 33 protons and 42 neutrons?
Arsenic Arsenic as 33 protons and 42 neutrons in its nucleus giving it an Atomic Number of 33 and an atomic mass of 75. Arsenic is in Period 4 of the Periodic Table because it has 4 electron shells.
What has 16 protons and electrons?
If a sulfur atom has 16 protons, 16 electrons, and 16 neutrons, what is its atomic mass?
What isotope has 16 protons 18 electrons 16 neutrons?
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
What has 12 protons and 12 neutrons?
Magnesium atoms So you might account for this isotope problem by saying that about 79% of all Magnesium atoms have 12 neutrons, 12 protons, and 12 electrons.
What is the element with 26 protons?
iron In February, we have selected iron, the most abundant element on Earth, with chemical symbol Fe (from the Latin word “ferrum”) and atomic number 26. A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus.
What has 36 electrons 42 neutrons and 33 protons?
Hence, the given element is arsenic.
What has 16 protons and 15 neutrons?
Answer and Explanation: The element with 16 neutrons, 15 protons, and 15 electrons is phosphorus.
Which of the following has 16 protons 17 neutrons and 18 electrons?
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur, S .
What has 12 protons and 25 neutrons?
Magnesium, in its elemental form, has 12 protons and 12 electrons. The neutrons are a different matter. Magesium's average atomic mass is 24.305 atomic mass units, but no magnesium atom has exactly this mass.
What has 12 protons and 10 neutrons?
Magnesium Ion Magnesium Ion has 12 protons and 10 neutrons. Mg and has an atomic number of 12, which means 12 protons are in it.
What is the element with 30 protons?
Zinc is the first element of the twelfth column of the periodic table. It is classified as a transition metal. Zinc atoms have 30 electrons and 30 protons with 34 neutrons in the most abundant isotope.
What element contains 7 protons?
Correct answer: Nitrogen has atomic number seven, and is the only element that can have seven protons. The given configuration is for an isotope of nitrogen. Since there are eight neutrons, this atom would be for nitrogen-15.
What has 15 protons and 14 neutrons?
The element with 16 neutrons 15 protons and 15 electrons is phosphorus.
How many electrons does ca2+ have?
18 electrons Ca2+ represents an ion with 20 protons and 18 electrons. A calcium atom has 20 protons and 20 electrons. The 2+ charge next to the symbol indicates a loss of two electrons: 20-2=18.

How many protons are in ca2+?
20Calcium / Atomic number
How many neutrons does ca2+ have?
No. of neutrons = 40−20=20. Hence 20 neutrons are present in calcium.
Does Ca2+ have 20 protons?
This means that all calcium atoms contain 20 protons. A neutral atom of calcium will also have 20 electrons. The most common ionic form of calcium is Ca2+, which has a positive 2 charge. The Ca2+ ion, therefore, contains 18 electrons.
How many neutrons does Ca2+ have?
No. of neutrons = 40−20=20. Hence 20 neutrons are present in calcium.
