Why should we take care of our environment?
Why is it important that we consider recycling?

Explanation:

It is Important to take care of our environment because we live in it, we are the cause and the only cause of global warming and littering and so many other problems in our environment and we should be responsible to solve the problem we created for ourselves and our ecosystem.

We should consider recycling because it is a great way of getting already existing garbage reused and not wasted. (hope this helps!)

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
