Answer:
it will gain electrons to fill its outer shell
Explanation:
This element is boron which has 5 electrons.
Using the formula density = mass ÷ volume, I got my answer as 10g/cm^3 or 10g/mL
Answer:
To calculate the number of significant figures in a number with decimal,
start at the first non-zero digit in the number and count the total number of digits till the end
hence, in this number:
we will have 6 significant figures
Answer:
A FUSE is a type of conductor which protects the circuit by shorting it down when there is excess flow of current passing through it.
Explanation:
A fuse wire is made up of conducting materials such as alloy of tin and lead that has high resistivity. It has a low melting point of 200°C. It works based on the principle of heating effect of electric current. The functions of fuses include the following:
--> Fuses are made up of thin wire CONDUCTORS which interrupts or breaks the current flow of a circuit when in excess, thereby protecting the circuit from damage.
--> it prevents overload of current. In the event where too many appliances are connected to a single circuit, this can lead to overload which triggers a fuse to terminate the circuit connection.
--> It prevents total black-out: SWITCH-LIKE devices known as CIRCUIT BREAKERS share this function with the fuses. The nearest circuit breaks if any dysfunction occurs in the components of the circuit thereby preventing blackout.
