Two atoms that have a total of 20 electrons combined could be calcium (Ca) and potassium (K), as calcium has 20 electrons and potassium has 19 electrons. Alternatively, you could have two atoms of calcium, which would also sum up to 20 electrons. Another combination could be a calcium atom (20 electrons) and an oxygen atom (8 electrons) if we consider a different arrangement, but that would exceed the total.
What else can I help you with?
What is an atoms charge when it has 20 electrons 20 neutrons and 20 protons but then it loses two electrons?
This atoms charge would be +2. Electrons are negative, protons are positive, when they are in equal amounts they balance out to zero, when you lose electrons you have more protons, so the atom becomes positively charged.
What makes up calcium-40 ion with a charge of 2 plus?
Calcium-40 with a 2+ charge has lost two electrons, making it a Ca2+ ion. This ion contains 20 protons, as in all calcium atoms, and 18 electrons (since it lost two electrons).
How many valence electrons does isopropyl alcohol have?
Isopropyl alcohol, or isopropanol (C3H8O), has a total of 20 valence electrons. The carbon atoms contribute 12 valence electrons (3 carbon atoms with 4 electrons each), the hydrogen atoms contribute 8 valence electrons (8 hydrogen atoms with 1 electron each), and the oxygen atom contributes 6 valence electrons. Thus, when you sum them up (12 + 8 + 6), you get a total of 20 valence electrons.
When an atom is charged it is an ion. how many electrons are in O2?
O₂ refers to a molecule of oxygen, which consists of two oxygen atoms. Each oxygen atom has 8 electrons, so in total, O₂ has 16 electrons. If you are asking about the number of electrons in an ion of oxygen, such as O²⁻ (which has gained two extra electrons), then it would have 10 electrons per atom, totaling 20 electrons for the O²⁻ ion.
What is metal with 20 electrons?
The metallic element whose atoms contain 20 electrons each is calcium, with atomic number 20. (The number of electrons in a neutral atom always matches the number of protons, which is the definition of atomic number.)

How many electrons does calcium sulfate have?
The calcium ion has 18 electrons. The sulfate ion has 16 electrons from sulfur, 32 electrons from oxygen atoms and two from the charge. Altogether, a (molecule) of calcium sulfate has 68 electrons. * Calcium sulfate is not existing as molecules, 'formula unit' is a better phrase.
What makes up calcium-40 ion with a charge of 2 plus?
Calcium-40 with a 2+ charge has lost two electrons, making it a Ca2+ ion. This ion contains 20 protons, as in all calcium atoms, and 18 electrons (since it lost two electrons).

How many subatomic particles does calcium have?
Calcium atoms have 20 protons and 20 electrons. The number of neutrons varies with the isotope.
How many atoms do Ca have?
There are 20 protons in a calcium atom. You can find the number of atoms in any element by looking at the atomic number which is in the top right corner of the element's box on the periodic table. e.g. Ca 20 40.078

What is the ion notation for an atom with 20 protons and 18 electrons?
That particular atom will have a positive two (+2) charge. Charged atoms are more commonly known as ions.
What is metal with 20 electrons?
The metallic element whose atoms contain 20 electrons each is calcium, with atomic number 20. (The number of electrons in a neutral atom always matches the number of protons, which is the definition of atomic number.)
What is the ionic charge of neutral calcium that contains 20 protons 20 neutrons and 20 electrons and loses two electrons?
A neutral calcium atom that loses two electrons has a +2 charge.
How many electrons can beryllium lend?
2 because it has two outer shell electrons out of 8 (relevant rule only for the first 20 elements)
How do the atoms of calcium compare to the atoms of sodium?
Atoms of calcium have 20 protons and electrons, while atoms of sodium have 11 protons and electrons. Calcium is larger in size and has a higher atomic mass compared to sodium. Both atoms are metals and are part of the alkali earth and alkali metal groups, respectively.
