Answer:

The first 20 elements of the periodic table :

1.H —Hydrogen

2.He—Helium

3.Li—Lithium

4.Be—Beryllium

5.B—Boron

6.C—Carbon

7.N—Nitrogen

8.O—Oxygen

9.F—Fluorine

10.Ne—Neon

11.Na—Sodium

12.Mg—Magnesium

13.Al—Aluminum

14.Si—Silicon

15.P—Phosphorus

16.S—Sulfur

17.Cl—Chlorine

18.Ar—Argon

19.K—Potassium

20.Ca—Calcium

The valency of first 20 elements is as follows :-

1. Hydrogen (H) = 1

2. Helium (He) = 0

3. Lithium (Li) = 1

4. Beryllium (Be) = 2

5. Boron (B) = 3

6. Carbon (C) = 4

7. Nitrogen (N) = 3

8. Oxygen (O) = 2

9. Fluorine (F) =1

10. Neon (Ne) = 0

11. Sodium (Na) = 1

12. Magnesium (Mg) = 2

13. Aluminium (Al) = 3

14. Silicon (Si) = 4

15. Phosphorus (P) = 3, 5

16. Sulphur (S) = 2

17. Chlorine (Cl) = 1

18. Argon (Ar) = 0

19. Potassium (K) = 1

20. Calcium (Ca) = 2

Explanation:

First 20 elements in the periodic table start with H and end with Ca. The quickest way to remember the number of valence electrons is to form a relationship with the number of the group the element is located in.

According to Keynes, what type of economic policy is needed to return the economy to full employment when there is either a rece
FinnZ [79.3K]

Answer:

Option (B) is correct.

Explanation:

A recessionary gap is a situation in which the equilibrium level of real GDP is less than the full employment level. In this condition, the aggregate demand is lower and there is a shortage of aggregate demand. This shortage of aggregate demand will be corrected if there is an increase in the government spending or decrease in the taxes. This would increase the aggregate demand in the economy, and therefore, increase the real GDP and achieve the full employment level.

An inflationary gap occurs when the equilibrium level of real GDP is greater than the full employment level. There is a higher level of aggregate demand in the economy, so there is a need to lower down the government spending or to raise taxes in order to reduce the aggregate demand. This lower level of aggregate demand reduces the real GDP and achieve the full employment level.

Suppose a State of California bond will pay $1,000 eight years from now. If the going interest rate on these 8-year bonds is 5.5
svlad2 [7]

Answer:

the bond worth today is $651.60

Explanation:

The computation of the amount of bond worth today i.e. present value is to be shown below:

Present value = Amount ÷ (1 + interest rate)^number of years

where,

Amount = $1,000

Interest rate = 5.5%

And, the number of years is 8

Now placing these values to the above formula

So, the worth of the bond today is

= $1,000 ÷ (1 + 0.55)^8

= $651.60

hence, the bond worth today is $651.60
