Which of the following statement is correct economics?

The correct answer is b) In large measure, economics is the study of how people make choices.

Which one of the following statements is correct for the nature of oxides when we move in periods from left to right in the modem periodic table?

(d) The oxides become more acidic. Answer: Correct Option: – (c) The atoms lose their electrons more easily. As we move from left to right across the periods of the periodic table, the non-metallic character increases.

Which of the following statement is not a correct statement about the trends?

On moving from left to right across the period, the nonmetallic character increases. Hence the tendency to lose electrons decreases. So the given statement is incorrect.

Which of the following is the correct statement about the trends when going from left to right across the period of the periodic table?

Metallic character decreases and non-metallic character increases from left to right in a period. The statement that atoms lose their electrons more quickly is incorrect since the non-metallic character of the periodic table increases as we move from left to right across the periods.

Which of the following statement is correct GDP?

Which of the following statements is correct? Explanation: GDP at factor cost = Net Value Addition + Depreciation is correct. GDP at at factor cost is the sum of net value addition by all producers within the country. 4.

Which type of oxides are formed by metals?

Metals tend to form basic oxides, non-metals tend to form acidic oxides, and amphoteric oxides are formed by elements near the boundary between metals and non-metals (metalloids).

Which of the following statement about the modern periodic table is correct?

In the modern periodic table it consists of 18 vertical columns known as Groups and 7 horizontal rows known as periods. According to this definition, only option (c) matches.

How is real GDP different from GDP?

The main difference between nominal GDP and real GDP is the adjustment for inflation. Since nominal GDP is calculated using current prices, it does not require any adjustments for inflation. Using a GDP price deflator, real GDP reflects GDP on a per quantity basis.

What is the chemical symbol of oxide?

The oxide ion has the formula O2−. It is the conjugate base of the hydroxide ion, OH− and is encountered in ionic solids such as calcium oxide.

Which type of oxides are formed by non-metals?

When non-metals are combined with oxygen then neutral or acidic oxides are formed . Examples of acidic oxides are NO2,SO2 and examples of neutral oxides are NO, CO etc.

Where do you locate elements?

In the modern periodic table, noble gas elements are present in the group 18. Hence, you would locate the element with electronic configuration 2, 8 in the Modern Periodic Table in the group 18.

Which element is given ABCD and E with atomic number?

For B, C, D, the second shell is being filled, so they belong to the second period. For E, the fourth shell is being filled, so it belongs to the fourth period. So B, C, D belong to the same period. Therefore, the correct answer is option (B).

Which statement is correct about periodic table?

Answer: B. Explanation: elements are arranged in increasing order of atomic number i.e. number of protons.

What decreases across the period?

In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
