Help me please 1) information about the atomic structure (structure of the atom)

2) information about the periodic table of the elements and the classification of the elements​

an atom is the smallest unit of matter or a substance.

Explanation:

the structure of the

atom consists of electrons, protons, neutrons) which makes up the nucleus is more than a hundred thousand times smaller than it's atom but makes up 99.9% of the mass of the atom.

the protons are the positively charged particles. The neutrons are the negatively charged particles. The electrons are the negatively charged particles.

the first energy level consists of two electrons. the second energy level consists of eight electrons. the 3 energy level consists of eighteen electrons. the 4 energy level consists of thirty two electrons.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
