The Mendeleev and Mosley periodic charts have gaps for the as-then-undiscovered elements. Why do you think the chart used by Mosley was more accurate at predicting where new elements would be placed?

Moseley arranged the elements in order of their atomic number

Explanation:

Mendeleev arranged the elements in order of their atomic mass.

His table had gaps for the then-unknown elements, but it also had problems, because Co and Ni were out of order and so were Te and I.

The noble gases, most of the lanthanides and actinides, and none of the trans-uranium elements had then been discovered.

When Moseley arranged the elements according to their atomic numbers, the Ni-Co and Te-I anomalies disappeared.

The modern arrangement shows the elements unknown to Mendeleev highlighted in pink.

Using Moseley's chart based on atomic number, it became much easier for scientists to put newly-discovered elements in their correct places in the Periodic Table.

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

yes
