What happens when current passes through an electrolyte?
When current passes through an electrolyte, it causes chemical reactions at the electrodes. Positive ions move towards the negative electrode (cathode) and negative ions move towards the positive electrode (anode). This leads to the conversion of the ions into neutral elements or compounds at the electrodes.
Solid ionic compounds have very high melting points because they?
have strong electrostatic forces of attraction between the positive and negative ions in their crystal lattice structure. This strong attraction requires a significant amount of energy to overcome, resulting in high melting points.
What has extra electrons?
Atoms or ions that have more electrons than protons have extra electrons. This typically occurs in negatively charged ions or in atoms that have gained additional electrons through a chemical reaction.
Lattice energy is effected by all the following factors except what charge of ion size of ion or number of electrons shared in the chemical bond?
Number of electrons shared in the chemical bond. Lattice energy is affected by the charge of the ions and the size of the ions, as these factors determine the strength of the electrostatic interactions within the lattice structure. The number of electrons shared in the chemical bond is not directly related to lattice energy, as lattice energy is primarily influenced by the arrangement of ions in the crystal lattice.
Name parts of a cell and explain how they work together to produce a electric current?
The parts of a cell that work together to produce an electric current are the anode (positive terminal), cathode (negative terminal), and electrolyte. The anode releases positively charged ions into the electrolyte solution, while the cathode receives these ions and releases negatively charged ions. The flow of ions between the anode and cathode through the electrolyte creates an electric current.
What substances form hydrogen ions in water?
Chemical compounds called acids will do this.
What is The force of attraction that holds atoms or ions together?
The force of attraction that holds atoms or ions together is called a chemical bond. This bond can be formed by the sharing of electrons (covalent bond) or the transfer of electrons (ionic bond) between atoms. These bonds are crucial for the formation of molecules and compounds.
Are all salts elements?
No, salts are not elements. Salts are ionic compounds composed of positively charged ions (cations) and negatively charged ions (anions) that are held together by electrostatic forces. These ions can be composed of different elements from the periodic table.
When ionic compounds form the ions come together in a way that balance out the charges on the ions?
Yes.
What is the reason for colour in chemical compounds?
because the ions involved are of specific colors.
What are ionic compounds held together by?
Ionic compounds are held together by the electrostatic attraction between positively charged metal ions and negatively charged non-metal ions. This attraction results from the transfer of electrons from the metal to the non-metal, creating oppositely charged ions that are attracted to each other.
What holds different atoms or ions together in a chemical compound?
Chemical bonds hold different atoms or ions together in a chemical compound. These bonds are formed through the sharing or transfer of electrons between the atoms or ions.
How can one obtain polyatomic ions?
Polyatomic ions can be obtained by combining multiple atoms of different elements that are covalently bonded together. These ions have an overall charge and behave as a single unit in chemical reactions. They are commonly found in compounds such as salts and acids.
When compounds that are formed by ionic bonds decompose the products are usually what?
When compounds formed by ionic bonds decompose, the products are typically the separate ions that made up the original compounds. This decomposition process usually occurs when the ionic compound is subjected to heat, electricity, or chemical reactions that break the bonds holding the ions together.
How are the ions kept in place in ionic compounds?
In ionic compounds the ions are held in place in a lattice structure by ionic bonds. This is a type of chemical bond caused by the electromagnetic attraction of two oppositely charged ions.
What makes the ions stick together in an ionic bond?
In an ionic bond, oppositely charged ions are held together by the strong electrostatic attraction between them. The positive and negative charges attract each other, causing the ions to stick together and form a stable compound.
Polyatomic ions are metal or nonmetal?
Plyatomic ions are compound bonds of metal.Therefore, they are metals
