5. An element whose highest occupied s sublevel and a nearby d sublevel <br> contain electrons
Mumz [18]

Answer:

                    Transition Element

Explanation:

                     Transition elements are defined as those elements which can form at least one stable ion and has partially filled d-orbitals. They are also characterized by forming complex compounds and having different oxidation states for a single metal element.

                      Transition metals are present between the metals and the non metals in the periodic table occupying groups from 3 to 12. There general electronic configuration is as follow,

                                                   (n-1)d ¹⁻¹⁰ns ¹⁻²

The general configuration shows that for a given metal, the d sublevel will be in lower energy level as compared to corresponding s sublevel. For example,

Scandium is present in fourth period hence, its s sublevel is present in 4rth energy level so its d sublevel will be present in 3rd energy level respectively.

Hence, we can conclude that for transition metals the electron are present in highest occupied s sublevel and a nearby d sublevel .

All atoms of the same element:
34kurt

Answer:

have the same number of protons

Explanation:

Atoms of the same element will always have the same number of protons.

Protons are the positively charged particles in an atom which are located in the nucleus.

  • To recognize an atom, the number of protons is used.
  • The number of protons is the atomic number.
  • On the periodic table, atoms are arranged based on the number of protons.

The formation of a solid, also known as a _____, is an indication of a chemical change.
elena-14-01-66 [18.8K]

Answer: precipitate

Explanation: Chemical change is a change in which the chemical composition of the atoms changes. The following changes are seen when chemical reaction takes place:

1) Release or absorption of heat

2) Formation of solid or a precipitate

2AgNO_3(aq)+BaCl_2(aq)\rightarrow 2AgCl(s)+Ba(NO_3)_2(aq)

3) Change in color

4) Production of gas
