Answer:
They have electrons in their 3d- and 4s-orbital for bond formation.
Explanation:
d- metals or transition metal are metal which form ion with partially filled d-orbital. Examples are iron and manganese.
The metals have 2 electrons in their 4s orbital. If only this is used for bonding, they will form compounds where they have oxidation State of +2 as seen in MnO.
If two 4s and one of 3d electrons are used, oxidation state of +3 is formed as seen in FeCl3.
If two 2s electron I used with two 3d electrons, compound with oxidation state of +4 is formed as seen in MnO2
Answer:
50 kg
Explanation:
Data:
Mass of bicycle = 10 kg
F = 168 N
a = 2.8 m/s²
Calculation:
F = ma Divide each side by m, Then
m = F/a
= 168/2.8
= 60 kg
m = mass of bicycle + Naoki's mass. Then
60 = 10 + Naoki's mass Subtract 10 from each side
Naoki's mass = 50 kg
Answer:
2 electrons
Explanation:
Oxygen has 6 valence electrons and to be stable it needs 8. That means it needs 2 more electrons to have a full octet.
