What element has a proton 20 and electron 20?
calcium (Ca)
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 the name of an element with 20 protons 20 electrons and 20 neutrons?
calcium
The mass number of calcium which has 20 protons and 20 neutrons is. The mass number of calcium which has 20 protons and 20 neutrons is.
How many neutrons are present in an element with 20 protons 20 electrons and has a mass number of 40?
number of neutrons = 20 An atom of the calcium-40 isotope has 20 neutrons in its nucleus.
What is the mass number of an atom having 20 protons and 20 neutrons?
Now, in order for an atom to be an atom of calcium, it Must contain 20 protons in its nucleus. Always. The number of neutrons can vary, but the number of protons must always be equal to 20 for a calcium isotope. You are dealing with the calcium-40 isotope, 4020Ca .
Which of the following may contain 20 protons 20 neutrons and 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 Ca?
20Calcium / Atomic number
What is the atomic number of an atom with 20 protons 20 electrons and 22 neutrons?
The atom with atomic number 20 is calcium. Hence, the symbol for the atom having 20 protons and 22 neutrons is Ca. Note: The calcium atom has atomic number 20 that is the number of protons, while it has a mass number of 42, that represents the number of neutrons as, mass = protons + neutrons.

What is the atomic number and mass number of a calcium atom with 20 protons 20 neutrons and 20 electrons?
Solution : As X consists of 20 protons `rArr` atomic number, (Z) is 20. As number of neutrons = 20, mass number, (A) = atomic number + number of neutrons . `therefore` A = 20 + 20 = 40 `therefore` Mass number, (A) = 40 The element is calcium and can be represented as `””_20Ca^40`.
Which of the following is an isotope of the element with 20 protons p 20 and 22 neutrons and 22 )?
Calcium is the element with atomic number 20 and its symbol is Ca.
What is the identity of the element that has 20 protons?
The atom with 20 protons and the mass number of 40 is the original element and the atom with 20 protons and the mass number of 44 is the isotope. That’s why they are the same element, which is calcium, but different.
How many protons does Cao have?
Ca has 20 protons, so neutral it would have 20 electrons, but according to the charge, 2 electrons have been lost.
What elements has a mass number of 20?
The elements of the periodic table sorted by atomic mass
| Atomic Mass | Name chemical element | number |
|---|---|---|
| 39.948 | Argon | 18 |
| 40.078 | Calcium | 20 |
| 44.9559 | Scandium | 21 |
| 47.867 | Titanium | 22 |
What is the charge of an atom with 20 protons and 18 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.
