which element has the electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f14 6d8
salantis [7]

Answer:

Darmstadtium

Explanation:

An element with the electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p⁶7s²5f¹⁴6d⁸ has 110 electrons in its electron shells.

Since the element is a neutral atom, this number is also equal to its atomic number. Therefore, its atomic number is 110.

The element in the period table that has an atomic number of 110 is Darmstadtium, a d-block element, thus a transittion metal. It also belong to period 7 in the Periodic table of elements.

9966 [12]

Answer:

Ionic

Explanation:

Lithium is an alkali metal and form an ionic bond by donating an electron.

Fluorine is a halogen and forms ionic bonds by accepting an electron.

The electronegativity difference between lithium (0.98) and fluorine (3.98) is 3 Pauling units. Usually, when elements have a difference of 1.7 (or 2.0) Pauling units the bond is classified as ionic.
