What scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
What would its charge be Calcium has a atomic number of 20. It can form an ion by losing 2 electrons?
Calcium has an atomic number of 20, meaning it has 20 protons. By losing 2 electrons, it would have 20 protons and 18 electrons, giving it a net charge of +2.
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 neutrons and electrons are in an atom of calcium-42?
An atom of calcium-42 has 20 protons, as calcium has an atomic number of 20. Since the atomic number represents the number of protons in an atom, calcium always has 20 protons. Calcium-42 also has 22 neutrons, calculated by subtracting the atomic number from the atomic mass (42 - 20 = 22). The number of electrons in a neutral atom is equal to the number of protons, so a calcium-42 atom would have 20 electrons.
What is the element that has 20 neutrons?
Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
How many protons electrons and neutrons in calcium-44?
Ca-46 is an isotope of the calcium found on the periodic table. The atomic number is equivalent to how many protons the atom has and tells the identity of the element, if the number of protons is changed/ atomic mass number, the element would transmutate into another element. Thus, Ca always has 20 protons. Because it is not Ca++ or Ca- it is not changing the charge so no electrons are moving either. This means the number 46 is refering to a change in neutron in the nucleus of the atom, hence it is called an isotope. 46 is the number of protons plus neutrons so the isotope of Calcium has 20 protons, 20 electrons and 26 neutrons, or 46-20=26. Hope this clarifies things.
How many electrons would you need to make calcium neutral?
You would need 2 more electrons to make a calcium ion neutral, since calcium has 20 protons (+20 charge) and 18 electrons (-18 charge), resulting in an overall +2 charge. Adding 2 more electrons would balance out the charge to become neutral.
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.
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.
What is the nuclear symbol for an isotope that has 24 neutrons and 20 electrons?
The nuclear symbol would be ^44Ti, representing the element titanium, since the atomic number (number of protons) is 22 (20 electrons + 2 protons) and the mass number (protons + neutrons) is 44 (22 protons + 24 neutrons).
If calcium lost two electrons it would have the same number of electrons as?
If calcium lost two electrons, it would have the same number of electrons as argon. Calcium has 20 electrons in its neutral state, and losing two electrons would leave it with 18 electrons, which is the same as argon.
If a calcium atom has 20 protons and 20 neutrons and 18 electrons what is the magnitude of it's charge in coloumbs?
The charge of a calcium atom with 18 electrons will be +2 elementary charges since it has 20 protons and 18 electrons, resulting in a net positive charge. Each elementary charge is approximately 1.602 x 10^-19 Coulombs, so the total charge of the calcium atom would be 2 * 1.602 x 10^-19 Coulombs.
