BTEC Applied Science Unit One Chemistry – Complete Questions and Answers 2023. How many electrons can each orbital hold? correct answerTwo
How many electrons can be held in each sub shell? correct answerS - 2
P - 6
D - 10
F - 18
Put the sub shells in order do their energy, lowest to highest ...
Where does ionic bonding occur?l correct answerbetween metals and non-metal
What is electron spin? correct answerElectrons have two states, spin up and spin down. In an orbital
each electron will be in a different spin state
How do we form an ion? correct answerPositive ions - cation - lose electrons
Negative ions - anion - gains electrons
What is an ionic lattice? correct answerA regular arrangement of positive and negative ions
What does the strength of an ionic bond depend on? correct answerIonic change ( the higher the charge
the stronger the electrostatic force, however this force gets weaker as the radius of the ion increases)
Ionic radii ( the more shells the bigger the radius of the ion)
Explain why ionic compounds are electrically neutral. correct answerTotal positive charge of cations
equals the total negative charge of anions
Explain why ionic compounds can conduct electricity when molten or dissolved but not when solid
correct answerIn solids the ions cannot move
In molten or dissolved states the ions are free to move and carry a current
Why do ionic compounds have high melting and boiling points? correct answerBecause of the strong
electrostatic attraction between ions, it takes a lot of energy to separate the positive and negative ions
in a crystal lattice
Why does ionic radius increase down a group? correct answerincreasing number of energy levels
