Hi , basically the atmosphere is made up of 78% of nitrogen, nitrogen is very special and important because if the air was just made up of oxygen the air that we breath would be very flammable and toxic .That's why we have nitrogen.

1) A negatively charged ion is chloride

2) Moving from left to right, valence electrons increase by one.

3) The period number gives information about how many energy levels it has

4) Fluorine has a charge of 1–

5) Potassium and iodine form an ionic bond

The periodic table is an arrangement of elements into groups and periods based on their periodic properties.

In the periodic table, elements are arranged in groups and periods. There are 18 groups and 8 periods.

Chlorine is in group 17, there have seven outermost electrons hence the chlorine atom needs only one more electron in order to attain a stable octet. This is done by accepting one electron to form the negatively charged chloride ion.

As we move from one period to another, one extra electron is added to the outermost shell of elements. Hence, the valence electrons increases by one.

The period to which an element belongs shows you the number of shells or energy levels in the atom of that element.

Fluorine is in group 17. One electron is needed to achieve a stable octet. When an atom accepts one electron, its charge is 1–.

Bonding based on ionic charges occurs between metals and nonmetals. Potassium is a metal of group 1 and iodine is a non metal of group 17 hence they can bond together based on their ionic charges.

Serga [27]

Answer:

Efficiency = 5%

Explanation:

Given that,

Supplies energy to the bulb = 100 J

Transferred energy by the bulb = 5 J

We need to find the efficiency of the bulb. It can be given by "

\eta=\dfrac{\text{useful energy out}}{\text{useful energy in}}\times 100\\\\=\dfrac{5}{100}\times 100\\\\=5\%

So, the efficiency of the bulb is 5%.
