Answer:
1.The electonic configuration of elements and their position in the periodic table are related to each other, From the electronic configuration of the elements, we can determine the period and the group to which the element belongs
Let's consider, sodium with atomic number 11 and k, l, and M shells have 2,8,and 1 electrons. since, there are 3 principal energy levels so we concluded sodium belongs to third period M Shell(valance shell) has only 1 electrons. so sodium belongs to group 1.
2. Entire D-block elements are known as Transition Elements.
3. Group 17 is the halogen group.
4. Main group of elements are...... 1,2, and 13 through 18.
5. Group 18 are the noble gas elements .
12. a). Smaller

d). Softer
7. a). k › Ca › Ge › Br › Kr
b). Ra › Ba › Sr › Ca › Mg › Be
9. a). Ca(calcium) ion is smaller.
b). Cl(chlorine) atom is smaller.
c). Mg(magnesium) atom is smaller.
10. a). F(fluorine)
b). Sr(strontium)
c). Pb(lead)
d). At(Astatine)
Answer:
Capillarity , Adhesion and cohesion . The unique property of water enable life to exist . The most important property of water is movement of materials due to water , maintenance and growth and reproduction .
Explanation:
Answer:
The air pressure is 9.8 *10^4 pa
The water will rise to a height of 10.0 meter
Explanation:
Step 1: Data given
As a storm from moves in, you notice that a column of mercury in a barometer rises to 736 mm.
Step 2: Calculate the air pressure
The Pressure against the mercury column = h*d*g = 0.736 * 13593 * 9.81 = 9.8 * 10^4 Pa
Step 3: Calculate the height of the water
Let the Pressure the water column for same pressure is h meter : -
9.8 * 10^4 = h*d*g
=>9.8*10^4 = h*1000*9.81
=>h = 10.0 meter
The water will rise to a height of 10.0 meter
Because the pot isn’t water it just gets really hot and you can burn yourself if you touch it
The general form would be
Reactants ---> Products
