3 0
Cobalt is a Transition Element and it has a partially filled d-orbital. As given it has atomic number 27. In neutral state Cobalt has 27 electrons. These electrons are filled in following order,

                               1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d⁷

Or it can also be written as,

                                              [Ar] 4s², 3d⁷

Where; [Ar] is Argon with electronic configuration 1s², 2s², 2p⁶, 3s², 3p⁶.

When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bon
Morgarella [4.7K]

Answer:polar covalent bond

Explanation:

Compounds are formed ether by donating, receiving or sharing of electrons making the bonds between them to  be ionic, or covalent .

Now  according to the rule  of type of bond assignment due to electronegativity difference of atoms

---When the  electronegativity difference is less than 0.5,  the bond formed is nonpolar covalent.

---When   the  electronegativity difference is between 0.5 and 1.6, the bond is considered polar covalent

---When  the  electronegativity difference greater than 2.0, then the bond is ionic.

Therefore, When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bonded by  polar covalent bond eg HCl bond , CCL4 bond

Which two factors does the power if a machine depend on
Furkat [3]

The definition of mechanical power is


                       Power = (work done) / (time to do the work).


From that definition, it looks pretty much like the power of a machine

depends on work and time.

Answer:

Mixture of two elements

Explanation:

You can tell that it is an element since the atoms are only bonded to atoms of the same type.  It is a mixture since the molecules are together in solution but aren't bonded together.
