When an atom loses or gain this type of particle the mass nbr changes?
electrons
What happens to Calcium chloride in air?
When exposed to air, calcium chloride can absorb moisture and become hydrated, forming a white, powdery substance. It is hygroscopic, meaning it has a strong affinity for water molecules in the air. This property allows calcium chloride to be used as a desiccant to remove excess moisture from the air.
What is the atomic structure of Ca 2 plus?
40 Ca2+ Mass number is 40 Atomic number (proton number) is 20 therefore 18 electrons as calcium has lost 2 electrons to become a Ca2+ ions :D
When an atom loses an electron the mass of the at om?
The mass doesn't change because electrons are so light that its mass is not included in the AMU.proton = 1 amuneutron = 1 amuelectron = ~1/1837 amu
What is the atomic mass of Ca-43?
The atomic mass of Ca-43 is approximately 43 amu (atomic mass units). This value represents the total mass of an atom of calcium-43, taking into account the protons, neutrons, and electrons that make up the atom.
What is the mass of a calcium ion when it loses 2 electrons?
Imperceptably less than one with its full compliment. Electrons are very important particles, but they have almost no mass of their own.
What happens to the mass of an atom when it loses two electrons?
The mass become lower but the difference is not significant.
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
Is the change in mass significant when an object gains or loses electrons?
No, the change in mass is generally not significant when an object gains or loses electrons because electrons have a very small mass compared to protons and neutrons in the nucleus. The change in mass from gaining or losing electrons is usually negligible.
How many protons neutrons and electrons does Ca have?
Electrons have no relevant mass, and protons and neutrons both have the mass of 1u. If Calcium has the number 20, it has 20 protons (and electrons). It's mass is about 40u. Core Mass - Protons = Neutrons 40u - 20u = 20u, this means Calcium has 20 electrons, 20 protons and 20 neutrons.
When an atom loses or gain this type of particle the mass nbr changes?
electrons
What are the subatomic particles of calcium?
Calcium has 20 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a calcium atom = Mass number - 20
What happen when an atom forms an ion?
For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.
What is the mass of this atom of Calcium - 40?
The mass of a Calcium-40 atom is approximately 40 atomic mass units (amu). This value represents the total mass of the protons, neutrons, and electrons in the atom.

Why does calcium carbonate lose mass if heated?
Calcium carbonate loses mass when heated because it decomposes into calcium oxide (quicklime) and carbon dioxide. This decomposition reaction releases carbon dioxide gas, causing the mass of the calcium carbonate to decrease.
