The elements most likely are halogens because if we talk about manner of bonding they all are diatomic molecules and need one electron to fill their outermost shell. That is why they bond with other atom of own type and exist as diatomic molecule in pure state. However, all halogens are so reactive that they react with metals through strongest type of ionic bonds and form salts.
They all tend to form salts when they react with metals like NaCl and that is why they are commonly known as salt dormers.
They perfectly show significant trends in some properties like atomic radius increases from top to bottom, boiling and melting temperature increase down the group and electronegativity value decrease from top to bottom.
The elements belong to group 17.

The force of static friction acting on the boy is 333 Newtons.
Hence, option (d) 333N is the correct answer.
Given the data in the question;
- Weight of boy;

- Coefficient of static friction;

Force of static friction acting on the boy; 
<h3>Friction</h3>
Friction is simply referred as the resistance an object experience when moving or trying to move over another object. It can either by dynamic or static.
Static friction is the resistance experienced by a body at rest.
Coefficient of friction is the measure of how easily a body moves in relation to the other.
Static friction is expressed as;

Where
is the normal force and
is the coefficient of static friction.
We substitute our given values into the equation above

The force of static friction acting on the boy is 333 Newtons.
Hence, option (d) 333N is the correct answer.
