Covalent bonds only form when electrons are shared between two nonmetals.
Answer:
i think it haven't impact because oxygen is very sensitive for our life and from plants there is so many kinds of food sources soo
Rules:
1) The oxidation number of a monatomic ion equals the charge of the ion.
2)The oxidation number of a Group 1 element in a compound is +1.
3) The oxidation number of a Group 17 element in a binary compound is -1.
4) The sum of the oxidation numbers of all the atoms in a neutral compound is 0.
KCl is an ionic compound. Consists of K+ ions and Cl- ions.
Oxidation of K= +1 (rules 1 and 2)
Oxidation of Cl= -1 (rules 1 and 3)
Rule 4 also applies- +1 + (-1)= 0- a neutral compound
Hope this helps :)
Explanation:
The answer is the first one
The following will increase the strength of a copper electromagnet;
Adding more loops to the wire
Increasing the current
Explanation:
An electromagnet, a device that transforms electric energy into magnetic energy, has its magnetic field induced by an electric current. This current must be AC (alternating current) and not Direct Current (D.C) for it to work. Increasing the number of coils in the electromagnet increases the number of field lines of interaction between the current and the paramagnetic material. Increasing the current also makes the magnetic stronger.
