Answer:
I believe:
vertebrate: hummingbird, tiger, lobster
invertabrate: lizard, octopus, mosquito
The correct answer is (c) It would have lower ionization energies than K and a lower electronegativity value than K
Explanation- The unknown element belongs to the alkali metals of periodic table. The alkali metal atoms have the largest size in a particular period of the period of periodic table. With the increase in the atomic number, the atom becomes larger.
Atomic radius decreases --> ionization energy increase---->Electronegativity increases. We can use this flow chart to compare the IE and EN of the element. As K have lower radii than the unknown element, so the IE and EN of K will be greater than the unknown element.
Ignition transformer
1.
Weight of the transformer is more.
2.
Voltage output of the transformer is from 10,000 volts
to 14,000 volts.
3.
Due to lower voltage output, fuel vaporization and
ignition will be slow.
4.
When there is a drop in voltage supply, the transformer
gets affected.
5.
Consumption of electricity is more.
Solid state igniter.
1.
Igniter weighs very light
2.
Igniter giver voltage output in the range of 14,000
volts to 20,000 volts
3.
Higher voltage output leads to faster vaporization of
fuel and ignition
4.
Very small affect is observed when there is a voltage
drop.
5.
Less electricity is consumed.
