Answer:
ions
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion.
Both atoms are bonded together electrostatic attraction occur between anion and cations.
In the second energy level, the highest energy subshell is 2p. The subshells are shown by the orbital quantum numbers.
There are four sets of quantum numbers that describe an electron in an atom which are;
- Principal quantum number
- Orbital quantum number
- Magnetic quantum number
- Spin quantum number
The values of the orbital quantum number which shows the energy subshell in which an electron is found must take on values from 0 to (n - 1).
Having said that, for an atom with more than one electron, the highest energy subshell in the second energy level corresponds to l =1 which is the 2p orbital. Remember that s p d f corresponds to 0 1 2 3 .

2. D/J
3. B/F
4. D or G/I
5. A
Explanation:
This is about sort of concentrations:
1- Molarity
Moles of solute in 1 L of solution
(we can also say, mmoles of solute in 1 mL)
2- Molality
Moles of solute in 1kg of solvent
3. mass %
grams of solute in 100g of solution
4. mole fraction
moles of solute or solvent per moles of solution
5. ppm
mg of solute in 1kg of solution
(we can also say μg of solute in 1 g of solution, or mg solute in 1L of solution)
