Why does fluoride have 2 ions in the compound cadmium fluoride CdF2?
The cadmium ion has a 2+ charge and each fluoride ion has a 1- charge, so two fluoride ions are needed to balance the 2+ charge of cadmium. Two F- ions provide a total negative charge of 2- to balance the 2+ charge of cadmium.
What is the formula for an ionic compound that contains the elements magnesium and chlorine?
The formula for an ionic compound containing magnesium and chlorine is MgCl2. Magnesium has a +2 charge, while chlorine has a -1 charge, so two chlorine ions are needed to balance the charge of one magnesium ion.
The charge on a chloride ion in AICI3 is?
The charge on a chloride ion in AlCl3 is -1. This is because aluminum typically has a +3 charge in ionic compounds, so in order for the compound to be neutral overall, each chloride ion must have a charge of -1.
Why does magnesium chloride have no overall charge?
Magnesium chloride has no overall charge because magnesium, a metal, has a +2 charge, while chloride, a nonmetal, has a -1 charge. When magnesium (Mg) donates two electrons to chlorine (Cl), each forms a stable ion (Mg²⁺ and Cl⁻) resulting in a neutral compound.
Is there such thing as a compound that has all the elements in it?
No, it is not possible for a compound to contain all the elements in the periodic table. Compounds are composed of specific elements in fixed ratios, and combining all the elements together would not result in a stable compound due to the differing chemical properties of each element.
When elements are more stable in a combined formwhich forms?
Each element can form stable, less stable or unstable compounds.
The atomic charges of each group?
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.
What do radioactive elements gain when they emit radiation?
They become slightly more stable with each decay until they become stable and stop decaying.
What is the charge on the most stable ion of each of the following elements O Al N you Mg Ba S and K?
O = 2- Al = 3+ N = 3- I = 1- Mg = 2+ Ba = 2+ S = 2- K = 1+
What three elements that form only one anion?
The three elements that form only one anion are fluorine, chlorine, and bromine. Each of these elements typically forms a single anion with a charge of -1: fluoride (F⁻), chloride (Cl⁻), and bromide (Br⁻), respectively. Their consistent -1 charge arises from their position in Group 17 of the periodic table, where they readily gain one electron to achieve a stable electronic configuration.
What charge will each ions have magnesium?
Magnesium typically forms ions with a +2 charge. This means it will lose two electrons to achieve a stable electronic configuration.
Does silica dioxide have a charge?
Silica dioxide (SiO2) is a neutral compound and does not have an overall charge. Each silicon atom is covalently bonded to two oxygen atoms, forming a stable structure with no net charge.
What is charges of atom?
An atom is electrically neutral because it has an equal number of protons (positive charge) and electrons (negative charge). The protons and electrons balance each other out, resulting in no overall charge for the atom.
Calcium has a plus 2 charge Fluoride has a -1 charge?
When these two elements form an ionic compound (either with each other or with any other elements) then those are the ions that they form, Ca+2 and F-1.
Describe the struggle between the president and congress when being in charge of the military?
They where calm not nervous stable and got along with each other
Define two what elements of the congressional committee system and explain how each influences the legislative process?
The following elements will not be able to be defined without knowing what the elements are. Information about what the elements are should be included.
Which group in the periodic table tends to form ions with a 2 charge?
An element should release two of its outermost electrons to obtain +2 ion. The elements in group 2A are the most likely elements to have this configuration. These are known as Alkali Earth Metals.The elements in the 2nd group have 2 valence electrons. Elements give away their valence electrons to get stable electron configuration. The elements in the 2nd group such as beryllium, magnesium, calcium, strontium, barium likely to have positive ion with charge of 2.Group II elements (the alkaline earth metals). This is because this particular group of elements have two extra electrons in their electronic configurations. They need to lose these two electrons to attain the stable noble gas configuration. So they will have a tendency to lose them to other atoms or group of atoms, in the process incurring a double positive charge (since there will now be two less electrons than protons). So Be, Mg and Ca will all form positive ions (cations) with a charge of +2. They are represented by Be2+, Mg2+ and Ca2+ respectively. But, other elements like copper and barium will also form cations of charge +2.
