well u take the Atomic Mass of Ca, 40, times it .5 and get 20 grams
What else can I help you with?
What does one atom of calcium weigh?
One atom of calcium weighs approximately 40 atomic mass units.
What weight of oxygen will react with 40 gram of ca?
For every 40 grams of calcium (Ca), 32 grams of oxygen (O) will be needed to react. This is based on the chemical formula for calcium oxide (CaO), where one calcium atom reacts with one oxygen atom to form one molecule of CaO.
What would happen if calcium atom loses 2 electrons?
If a calcium atom loses 2 electrons, it will form a calcium ion with a positive 2 charge (Ca^2+). This ion will have a stable electron configuration similar to that of a noble gas, making it more stable than the neutral calcium atom.
What is the mass in grams of a boron atom?
The mass of a boron atom is approximately 10.81 atomic mass units (amu). In grams, this would be about 1.80 x 10^-22 grams.
When naming the compound containing calcium and chlorine change the suffix of the atom name to?
When naming the compound containing calcium and chlorine, the suffix of the atom name changes to "-ide." Therefore, the compound would be named calcium chloride.
What does one atom of calcium weigh?
One atom of calcium weighs approximately 40 atomic mass units.
What weight of oxygen will react with 40 gram of ca?
For every 40 grams of calcium (Ca), 32 grams of oxygen (O) will be needed to react. This is based on the chemical formula for calcium oxide (CaO), where one calcium atom reacts with one oxygen atom to form one molecule of CaO.
What scientific element has 20 electrons?
Calcium has twenty electrons in each atom.
What atom make calcuim?
Calcium is an element, so each atom of calcium is calcium.
How many grams of calcium are in 19050.9 g calcium chloride?
The gram atomic mass of calcium is 40.08, the formula of anhydrous calcium chloride is CaCl2, showing that each formula unit contains one calcium atom, and the gram formula mass of anhydrous calcium chloride is 110.99. Therefore, 19050.9 grams of calcium chloride contains 19050.9(40.08/110.99) or 6.880 X 103 grams, to the justified* number of significant digits. ____________________________________________ *There may well be tables of gram atomic and gram formula masses more modern than the one I am using that would allow for more significant digits in the answer.
What is the symbol for the atom that has 40 electrons?
Technically, any atom could have 40 electrons, but it would have a very weird charge. However, Zirconium has 40 electrons without being an ion.
If a calcium atom has twenty protons then how many electrons would it have?
20 (any more or less and it would be an ion not an atom)
State the number of valence electrons in an atom of calcium?
A calcium atom has two valence electrons.
What is the Number of atoms of calcium?
one atom of sulphur and one atom of calcium
What would happen if calcium atom loses 2 electrons?
If a calcium atom loses 2 electrons, it will form a calcium ion with a positive 2 charge (Ca^2+). This ion will have a stable electron configuration similar to that of a noble gas, making it more stable than the neutral calcium atom.
