What is the name of an element with 20 protons 20 electrons and 20 neutrons?
Calcium
| Name | Calcium |
|---|---|
| Atomic Mass | 40.078 atomic mass units |
| Number of Protons | 20 |
| Number of Neutrons | 20 |
| Number of Electrons | 20 |
What is the total charge in an atom consisting 20 protons and 20 electrons?
2+ charge
For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge. It has the same number of electrons as atoms of the preceding noble gas, argon, and is symbolized Ca2+.
What is the charge of an ion with 20 protons and 20 neutrons?
2+
If it has got 20 protons, 20 positively charged, massive nuclear particles, the element is calcium by defintion, i.e. Z , the atomic number = 20 . The neutral metal has 20 electrons; the metal can ionize to form caclium ion, Ca2+ .
What is the mass number of an atom that consists of 20 protons 20 neutrons and 18 electrons?
C) Correct. Because the mass number of an atom is the sum of proton number and neutron number of the atom. So, 18 + 20 = 38.
What is the symbol of an ion with 20 protons 20 neutrons and 18 electrons?
Ca2+
Ca2+ represents an ion with 20 protons and 18 electrons.
How much electrons does BR have?
The Br− ion has 36 electrons.
What has 18 protons and 18 neutrons?
Argon
| Name | Argon |
|---|---|
| Number of Protons | 18 |
| Number of Neutrons | 22 |
| Number of Electrons | 18 |
| Melting Point | -189.3° C |
What is the ion with 20 protons and 18 electrons?
What element has 16 protons and 18 neutrons?
sulfur
The atomic number of sulfur is 16. The ion has 18 electrons that mean sulfur carries the charge of -2.
What element has 20 protons and 20 electrons?
Because there is one proton more than electrons, the charge of a substance is +1. 2) Answer is: All atoms are electrically neutral. For example, atomic number of calcium is 20, it means that it has 20 protons and 20 electrons, so atom of calcium is electrically neutral.
What is the number of neutrons in an element?
The atomic number of the element equals the number of protons. Calculating the number of neutrons then becomes atomic mass of the isotope minus the atomic number of the element equals the number of neutrons. For uranium-235, atomic number 92, the number of neutrons is 235-92=143, or 143 neutrons.
How many electrons and neutrons are in the Ca2+ ion?
There are total 20 electrons present in calcium as it is calcium ion there is +2 charge it means it now has 18 electrons with it. So, 40-20=20. Therfore there are 18 electrons,20 neutrons and 20 protons present in calcium ion.
