Answer:
Early transition metals- found on the left side of the periodic table (group 3-7), so called because they form the first part of the transition phase.These metals have less electrons than late transition metals, therefore their last valance matches their group number. Examples of early transitions metals are,Scandium, Titanium, and Manganese
Late transition metals- fast reacting metals, because their maximum valance shells are full, therefore having accessible oxidation states.Examples are Nickle, Silver, and Cobalt
Explanation:
Transition metal found in the middle of the periodic table. The IUPAC defines these metals,as metals whose atoms have a relatively full d-shell
Early and late transition metals are different due to their oxidation states.
3*40+3*2*35.5=333* Avogadro’s number =
1.98*10^25
An aerosol mixture of particulates and sulfur compounds form a grayish-colored substance that is called <u>industrial smog</u>.
<h3>What is Particulate Matter?</h3>
Airborne particulate matter (PM) is a composite of several chemical species rather than a single contaminant. It consists of a complex mixture of solids and aerosols, including dry solid particles, liquid-coated solid cores, and minute liquid droplets. Particles can contain inorganic ions, metallic compounds, elemental carbon, organic compounds, and chemicals from the earth's crust. They can vary greatly in size, shape, and chemical makeup. For the goal of regulating air quality, the particle diameter is used.
Those that have a diameter of 10 microns or below (PM10) are inhalable and can have a negative impact on health. Particles with a diameter of 2.5 microns or less are considered to be fine particulate matter (PM2.5). Consequently, a percentage of PM10 is made up of PM2.5.
