Ionization energy of atoms decrease as we move down a column on the periodic table.
Answer: Ionization energy
<u>Explanation:
</u>
The periodic table consists of elements arranged in rows (periods) and columns (groups). The arrangement of elements in a column are made based on the increasing order of atomic radii from top to bottom of column.
As the atomic radii increase in group from top to bottom, the number of electrons increase along the group lead to shielding effect. Since the count of valence electrons are same for all elements in a group, the effective nuclear charges also same.
But the increase in the atomic number lead to shielding and increase in electrons occupied in farther shells from nucleus. This leads to deduce ionisation energy when move down a group.
Answer:
Excessive use of fertilizers and pesticides by farmers in agriculture to enhance crop yield is detrimental to environment and human health. Fertilizers and pesticides use has led to the problem of air, water and soil pollution.
Answer:
Explanation:
1 mL = 0.000264 gallons
<em><u>Multiplying both sides by 75</u></em>
75 mL = 0.000264 * 75 gallons
<h2>
75 mL = 0.02 gallons</h2>
When convergent happens:
•Deep ocean trenches
• volcanoes
• mountains
• earthquakes
When divergent occurs:
• new oceanic crust forms
• submarine mountain range
• volcanoes
• earthquakes
When transform occurs:
• faults
• earthquakes
• linear valleys
• stream beds split in half
