Answer:
6
Explanation:
p orbital can hold up to six electron. Argon electron configuration will be 1s²2s²2p⁶3s²3p⁶
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.
It is either concave lens or mirror but since this is reflecting out rather than reflecting back it has to be concave lens. hope that helps! :’)
Answer:

Explanation:
The cation contains 51 protons and 48 electrons. The electrons are only lost not protons, so the element which corresponds to atomic number 51 is the cation which is Antimony (Sb).
Also, the charge on the cation is 51 - 48 = 3
This is because neutral atom contains the same number of electrons as protons.
Given the anion has one-third protons as cation which means thta:
Number of protons in anion = 
This corresponds to chlorine atom. The electrons are 1 greater than protons means that it has gain 1 electron.
So,
Sb Cl
3 1
Cross multiply the valency.
So, formula is
