What else can I help you with?
When you have Ca2 plus plus in chemistry what does the 2 plus signs mean?
The 2 plus signs indicate that the calcium ion (Ca2+) has a charge of +2. This means that the calcium atom has lost 2 electrons, giving it a positive charge of 2. It is an ion that is positively charged and forms in certain chemical reactions.
Calcium plus carbon plus oxygen plus oxygen plus oxygen equals?
Calcium plus carbon plus oxygen plus oxygen plus oxygen equals calcium carbonate (CaCO3), which is a chemical compound that forms when calcium reacts with carbon and oxygen.
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, the calcium ion Ca+2 has fewer electrons than the neutral calcium atom. The calcium atom has 20 electrons, while the Ca+2 ion has 18 electrons because it has lost two electrons to become positively charged.
Calcium oxide (CaO) forms when an atom of calcium loses two electrons giving it a plus 2 charge and an atom of oxygen picks up two electrons giving it a and ndash2 charge. What is calcium oxide?
Calcium oxide (CaO) is an ionic compound formed from the reaction between calcium and oxygen. When a calcium atom loses two electrons, it becomes a Ca²⁺ ion, while an oxygen atom gains two electrons to become an O²⁻ ion. These oppositely charged ions attract each other, resulting in the formation of CaO, which is a white, solid compound commonly used in construction and as a chemical feedstock.
What is the difference between an atom like Ca and an ion of an atom like Ca2 plus?
An atom of calcium (Ca) has a neutral charge due to an equal number of protons and electrons. In contrast, a calcium ion (Ca²⁺) is formed when a calcium atom loses two electrons, resulting in a positive charge. This loss of electrons alters its chemical properties and makes it more reactive, as it seeks to regain stability by attracting electrons from other atoms. Thus, the key difference lies in their charge and electron configuration.
Which atom is most likely to form a cation with a charge of plus 2?
An atom with two valence electrons, such as calcium (Ca), is most likely to form a cation with a charge of plus 2 by losing both electrons to achieve a stable octet configuration.
What is the word equation for calcium plus hydrochloric acid plus?
The word equation for the reaction between calcium and hydrochloric acid is: calcium + hydrochloric acid → calcium chloride + hydrogen gas.
What kind of bond is Ca plus 2CI?
Ionic bond. Calcium (Ca) is a metal and chlorine (Cl) is a nonmetal. The transfer of electrons from the calcium atom to the chlorine atoms results in the formation of Ca2+ and 2Cl- ions, which are held together by electrostatic attraction.
What is the solid product of calcium chloride plus sodium carbonate equals what plus sodium chloride?
Calcium carbonate.
Why is the calcium ion Ca2 plus more stable than the calcium atom Ca?
All atoms want to have full valence shells and calcium has 20 electrons: two on the first energy level, 8 on the second, 8 on the third and 2 on the fourth. If it loses two and becomes Ca2+ it will have a full valence shell as it will have eighteen electrons with 8 on the third energy level.
Is calcium neutral?
An inert atom or molecule does not react at all with other molecules/atoms. The only inert atoms are the noble gases, group 18 in most periodic tables. Calcium is certainly not inert; in fact, it is the third most reactive element according to the reactivity series of metals.
What is calcium plus hydrogen plus hydrogen?
HCl and SO2
