How many protons neutrons and electrons are in CA?
Calcium is the first (lightest) element to have six naturally occurring isotopes. Calcium-42 is composed of 20 protons, 22 neutrons, and 20 electrons.
Does CA have 20 protons?
Atoms that have a fewer number of electrons than protons, have a net positive charge, such atoms are called positive ions, or cations. For example, calcium (Ca) has an atomic number of 20. This means that all calcium atoms contain 20 protons. A neutral atom of calcium will also have 20 electrons.
What is CA number of neutrons?
Atomic elements in calcium The number of neutrons will be the same as the number of protons: it is also 20.
What is CA number of electrons?
20 electrons In order to write the Calcium electron configuration we first need to know the number of electrons for the Ca atom (there are 20 electrons).
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 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 element has 16 protons and 18 electrons and 18 neutrons?
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur, S .
What element has 18 protons and 22 neutrons and 18 electrons?
Argon The chemical symbol for Argon. A 2 dimensional representation of a Argon atom with 18 protons and 22 neutrons in the nucleus and 18 electrons orbiting the nucleus.
How do you find number of protons?
The number of protons in an atom is equal to the atomic number of the element. For example, let's use oxygen. According to the periodic table, oxygen has the atomic number eight. The atomic number is located above the element's symbol.
What is number of protons and neutrons?
The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons.
What has 18 protons and 22 neutrons?
Argon has 18 protons and 22 neutrons in its nucleus giving it an Atomic Number of 18 and an atomic mass of 40.
