Select the correct scientist for each of the following advances in creating the modern periodic table.
sergey [27]

Answer:

Lavoisier; Newlands; Moseley

Explanation:

In 1789, Antoine Lavoisier grouped the elements into gases, nonmetals, metals, and earths.

In 1865, John Newlands developed the Law of Octaves. He stated that "any given element will exhibit analogous behaviour to the eighth element following it in the table."  

In 1914, Henry Moseley found a correlation between the X-ray wavelength of an element and its atomic number. He was then able to restructure the periodic table according to atomic numbers.

What happens when two atoms form a chemical bond?A) Two atoms fuse together to form a chemical bondB) The atoms share or transfe
Assoli18 [71]

Answer:

B

Explanation:

A chemical bond is formed when there is a transfer or sharing of electrons. When there is a transfer, what we have is that the electrons completely leave the outermost shell of an atom, usually metal to the outermost shell of another atom, usually a nonmetal. This particularly alters the electronic configuration of these atoms. This is ionic or electrovalent bonding

Now, electron sharing is also another way of chemical bond formation. Electrons might be shared between two atoms in a case principally known as covalent bonding. The electrons here are controlled by the 2 nuclei
