In the reaction of calcium with chlorine which atom is oxidized?
calcium + chlorine yields calcium chloride oxidation means loss of electrons, it's the calcium atom the oxidizes into the calcium cation +2. the chlorine is being reduced from chlorine neutral to chloride -1 anion.
How many atoms does 2NaCl have?
Na is sodium Cl is chlorine NaCl is sodium chloride (table salt)
Why does one calcium atom combine with two chlorine atom?
calcium and chlorine combines to produce CalciumChloride (CaCl2) as chlorine needs 1 electron to complete its octate... and calcium needs to lose 2 electrons to stablized.. therefore 2 atoms of chlorine react with a single atom of calcium to stablized. Atomic numbers are as follow : Calcium 20 Chlorine 17
What is the electron arrangement in a sodium atom?
the structure of an atom goes like 2, 8, 16, 32 (these are the maximum numbers an orbit can hold) and so on. Since the atomic number of Sodium (Na) is 11, the structure, or electronic configuration, is 2, 8, 1 because 2 plus 8 plus 1 equals 11.
How many chlorine atoms are in MgCl2?
Three. Two chlorine atoms and one magnesium atom.
Why do we say the electronic structure of a chlorine atom is 2 8 7?
The simplified electronic configuration is called "2, 8, 7" because there are 2 electrons in the first shell, 8 in the second and 7 in the third, incomplete, shell.
What atom has the electronic structure 2 8 6?
Sulfur
What is the electronic structure of an atom with a proton number 5 and a nucleon number 11?
In a neutral atom, the number of electrons is the same as the number of protons. The electronic structure of an atom with five electrons would be 2, 3. The electron configuration would be 1s22s22p1.
How many electrons are in the third level of a chloride atom?
8 The structure of a chlorine atom is 2, 8, 7. As an ion, it gains 1 electron to have a full outer shell, hence 2, 8, 8 and a -1 charge.
How many electrons are in the third energy of a magnesium atom?
If you are talking about the electronic structure, which is 2.8.2. This would therefore mean that there are 2 electrons in the outer shell of magnesium.
Why is calcium oxide CaO but calcium chloride is CaCl2?
in calcium chloride each calcium atom needs to lose two electrons but each chlorine atom needs to gain only one electron. This means that two chlorine atoms react with every one calcium atom to form calcium chloride. So the formula for calcium chloride is CaCl2.ca = proton number is 20 so the structure would be 2, 8 ,8 ,2cl = proton number is 17 so the structure would be 2 , 8,7To make it stable calcium has to lose 2 electrons and chlorine has to gain an electron. However if you add 2 to 7 in the chlorine it will make 9 so it will still be unstable therefore you need two chlorine atoms to share out the 2 atoms in calcium.
How many atoms are hydrochloric acid?
The answer is 2. 1 atom of Hydrogen and 1 atom of Chlorine.
What is the electronic arrangement of chlorine?
The electronic arrangement of chlorine is 2, 8, 7. This means that chlorine has 2 electrons in its first energy level, 8 electrons in its second energy level, and 7 electrons in its outermost energy level.
How can magnesium give away 2 electrons to chlorine?
One, but there is a catch. One magnesium atom will combine with two chlorine atoms to make magnesium chloride (MgCl2). The magnesium will give one electron to eachof two chlorine atoms to create this metal salt.
How may potassium atoms do you think combine with a chlorine atom?
2
what kind of compound is magnesium chloride what happens to electrons during the formation of the compound what hold the atoms together in the compound?
In MgCl², Magnesium has 12 electrons, and its electronic configuration can be written as 2,8,2. Thus Magnesium has two electrons in its outermost orbit or it can be said that Magnesium has 2 valence electrons.In MgCl², each Chlorine atom has 17 electrons and its electronic configuration can be written as 2,8,7. Thus each Chlorine atom has seven electrons in its outermost orbit or it can be said that each Chlorine has 7 valence electrons.Magnesium wants to give away its two valence electrons to complete its octet by having 8 electrons in its outermost orbit attaining the electronic configuration of its nearest inert gas Neon. And each chlorine atom wants to complete its octet by adding one more electron in its outermost orbit so that it can have 8 electrons in its outermost orbit attaining the electronic configuration of its nearest inert gas Argon. So, we see that Magnesium wants to lose two electrons and each Chlorine atom wants to add one more electron in their outermost orbit Thus, Magnesium transfers its two electrons to two Chlorine atoms (one electron to each Chlorine atom) and thus Magnesium obtains +2 charge and each chlorine atom acquires −1 charge and ionic bonds are formed between the atoms of the molecule.An eletrovalent compound or ionic compound is formed when one atom in the compound transfers its electrons from itself to its neighboring atom. In MgCl², Magnesium transfers its two electrons to its neighboring chlorine atoms, and forms two ionic bonds between the atoms. Thus, MgCl² is an electrovalent compound or an ionic compound.
In the reaction of calcium with chlorine which atom is oxidized?
calcium + chlorine yields calcium chloride oxidation means loss of electrons, it's the calcium atom the oxidizes into the calcium cation +2. the chlorine is being reduced from chlorine neutral to chloride -1 anion.
