The atomic mass of an atom is calculated by adding up protons and neutrons
<h3>Further explanation
</h3>
There are two components that accompany an element, the mass number and atomic number
Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons
The charge of 1 proton is equal to a charge of 1 electron but has a different sign
The proton is positively charged (+1), the electron is negatively charged (-1). and neutrons not charged (neutral)
The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.
Atomic number = number of protons = number of electrons
⇒ neutral number
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Number of Neutrons
Answer:
Yes, we can separate the liquids from solutions using distillation.
Explanation:
In distillation, the components or substances are separated from a liquid mixture by selective boiling and condensation. Distillation can result in substantially complete separation (near-pure components), or it can be a partial separation that increases the concentration of the selected components in the mixture. In both cases, the process takes advantage of the differences in the relative volatility of the components of the mix. In industrial chemistry, distillation is a unitary process of universal practical importance, but it is a process of physical separation, not a chemical reaction. Distillation is also be used to separate a solution from two or more liquids or fractions. They are called miscible liquids and must have different boiling points, e.g. B. ethanol and water or fermented fruit juice. A capacitor is used. A mixture is heated to just above 80 degrees Celsius (the boiling point of ethanol is 79 degrees Celsius). Ethanol evaporates and condenses. It can be collected in a cup. The water remains in the balloon.
Silver has one valence electron and oxygen has 6 electrons in the outermost shell. Ionic bonds are formed by the transfer of electrons from a metal to a non metal.
atoms are most stable when they complete their outermost shell and complete the octet. This is when their s and p subshells in the outermost shell are complete, eight electrons hence complete octet.
silver has one valence electron so to become stable it will lose that valence electron and transfer it to oxygen. Oxygen has 6 valence electrons so to become stable it needs 2 electrons to complete its octet.
One silver atom gives one electron each, since oxygen needs 2 electrons ,
2 silver atoms are needed to form an ionic bond.
Ag will become cation - Ag⁺ and Oxygen will become an anion - O²⁻
ionic bond is formed due to the electrostatic attraction between oppositely charged ions
ionic compound - Ag₂O
2 silver atoms needed for one oxygen
