Water is often referred as a <span>universal solvent </span>because it is capable dissolving much more solutes as compared to any other solvent. This is because, water is a high polar molecule. In water, H has partial positive charge while O has partial negative charge.
Due to this, water favors dissociation of molecules into positively and negatively charged ions. Positively charge ions gets attracted towards oxygen i.e. negatively charges, while negatively charged ions get attracted towards positive end of water molecule.
However, it is worth nothing that, despite water being referred as universal solvent, many compounds are insoluble or partially soluble in water. For instance, most of the hydroxide displays poor solubility in water.
The number is is surely 1
Sodium ions and sulfate ions shall be present in the solution.
Answer is: 1 × 10⁻¹⁰ meter or 0.0000000001 meter.
The atomic radius is a measure of the size of the atom.
It is distance from the center of the nucleus of atom to the boundary of electron cloud.
The radius of atoms is between 30 and 300 pm (10⁻¹² m) or between 0.3 and 3 angstroms (10⁻¹⁰ m).
The radius generally decrease along each period of the Periodic table.
Your answer is A....They have the same number of protons and neutrons, but a different number of electrons. They have the same number of protons and electrons, but a different number of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers.....
