"These" should be referring to Alkali Metals.
They include metals such as Lithium, Sodium, Potassium etc.
They're classified as Group I elements because they all have one outmost shell electrons. This is why these metals are so reactive because they only need to lose one electron in order to achieve the octet of electrons (or duplet for Lithium), which means complete outmost shell electrons (2 or the 1st shell, others are 8).
The reason why they're especially reactive to Halogens (Group VII) elements are that Halogens have 7 outmost shell electrons, which only needs one more electron in order to get to the octet of electrons. So, if an Alkali metal reacts with a Halogen, the metal would give one of their electrons to the Halogen, that way, both of the elements can have an octet of electrons (or duplet).
Answer:I searched it up but i did understand it, it said something bout how they would not be able to service cuz I think the might lose food or something like that and just from my opinion they are supposed to live in the cold I don’t think they’ll be able to survive the hotness.
Explanation:
Answer:
C) none of the species would survive
Explanation:
clam only goes down to a pH of 4.5
The symbol Al+3 is a cation. Therefore giving us the correct answer being option B. cation.
Hope this helps! :)
