Answer:
Non metals join to form covalent bond.
Explanation:
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
Both atoms bonded through covalent bond.
In Cl₂ both chlorine atoms are bonded through the covalent bond.
Answer:
i can only help with 2 :( atimic mass is: 35.453 and number of electrons is:17
Explanation:
Distance and time is needed for determining speed
Answer:
Electric Current
This is a flow of electrons (such as the flow of electrons in a wire to light up a lamp).
Insulator
These stop the electricity from flowing (think rubber and glass).
Resistance
This is slowing the flow of electrons (the current) and where some of the electrons' energy gets converted into heat.
Conductor
These allow electricity to flow easily through them (think copper and aluminum).
