Which element is in the d-block of the
periodic table?
Selenium
Antimony
Tantalum
Lead - ANSWER-
Tantalum
Explain how ions are accelerated, detected and have their
abundance determined in the time of flight (TOF) mass
spectrometer - ANSWER-Ions accelerated by electric field
Ions hit the detector gains an electric and forming a current
Abundance detected by size of current
Suggest one reason why the experimental value is very
different from the data
book value 1 mark - ANSWER-Heat loss to the
surroundings
Name the type of bond formed between N and Al in H3NAlCl3
and explain how
, this bond is formed 2 marks - ANSWER-
Covalent bond
Shared pair of electrons
from N
Explain how the value of the Cl-Al-Cl bond angle in AlCl3
changes if at all on formation of the compound H3NAlCl3 2
marks - ANSWER-Al surrounded by 4 electron pairs
(tetrahedral)
Cl-Al-Cl decreases from 120 to 107 in H3NAlCl3
Ions of two isotopes of iron are
53Fe2+ 56Fe2+
Which statement is
correct?
- the ions of both the isotopes have configuration 1s2 2s2 2p6
3s2 3p6 4s2 3d6
- the ions of both the isotopes contains 26 neutrons
- 53Fe2+ has fewer protons that 56Fe2+
- after acceleration to the same kinetic energy 56Fe2+ will move
more slowly that 53Fe2+ - ANSWER-after acceleration to the
same kinetic energy 56Fe2+ will move more slowly that
53Fe2+
Which of these decreases down Group 2?
