Answer:
The element iodine forms an anion with the charge -1. The symbol for this ion is I⁻¹, and the name is iodide. The number of electrons in this ion is 7.
Explanation:
Hello,
In this case, we have to consider iodine has the capacity to accept the electrons lost by other elements such as metals or hydrogen by becoming negatively charged. Such phenomena makes iodine to form an anion (negatively charged) with the charge -1, since it only needs one electron to attain the octet. Moreover, the symbol of such ion is I⁻¹ and its name is iodide. By cause of the aforementioned, the number of electrons it has is 7 since at its outer shell seven electrons are found (see electron configuration Kr,5s²,5p⁵).
Best regards.
When something combines the other is said to be complementary.
Explanation:
Complementary is mainly referred to as combination , that is, when one component goes along with the other. One of the day to day example of a complementary good is bread and butter because bread goes along with butter and thus it makes a good combination.
Complementary in English Grammar means to develop a link . In English Grammar complement falls under a clause. There are three type of complements such as subject complement, object complement as well as adjective complement.
By state of matter I assume you mean solid, liquid, gas, in which case the answer would be C.
the behaviour of molecules:
- in a solid is low energy with limited activity where molecules only vibrate, cannot mould to shape of container
- in a liquid is with moderate energy, with molecules flowing over the top of one another, and thus can mould to the shape of the container
- in a gas is high energy with much activity, molecules "fly" around the container they are in and can be compressed
Answer:
The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side.
Explanation:
How do you balance equations?
In general, however, you should follow these steps:
1. Count each type of atom in reactants and products.
2. Place coefficients, as needed, in front of the symbols or formulas to increase the number of atoms or molecules of the substances.
3. Repeat steps 1 and 2 until the equation is balanced.
Change in energy is E=hc/wavelength of emitted photon
