Anonymous users2024-02-081) Seven periods, the number of elements is 2, 8, 8, 18, 18, 32, 32, if a and b are in the same group a.
If b is in the previous period of a, then b should be in the 1st, 3rd, 5th period atomic number 1, 11,37 If b is in the next period of a, then b should be in the 2nd, 4th, 6th period atomic number 3,19,55 if a and b are in the same group a.
If b is in the previous period of a, then b should be in the 3rd,5th period atomic number 17,53 if b is in the next period of a, then b should be in the 2nd, 4th, 6th period atomic number 9,35,852) 2nd and 3rd period y-x = 1
The 4th and 5th cycles y-x = 11
Cycles 6 and 7 y-x = 15
If you take a closer look at the periodic table, you'll see that it's pretty straightforward.

Anonymous users2024-02-06A piece of bronze is placed in a cube glass sink with a bottom side of 2 decimeters, and the water rises by 1 decimeter. If this piece of bronze were to be made into a cylinder with a base diameter of 10 centimeters, how many centimeters would it be high?
Bronze volume = 2 2 1 = 4 square decimeters.
Radius of the bottom surface of the cylinder = 10 2 = 5 cm = decimeters.
The bottom area of the cylinder = square decimeters.
Height = 4 dm = 51 cm.
2) What is the base area of a cube with an edge length of 10 cm, and its volume is equal to the volume of a cylinder with a height of 4 cm?
The base area of the cylinder = 10 10 10 4 = 250 square centimeters.

S bottom = 1 2 r = 1 2 * * 5 = square centimeter v copper = s bottom * h = 4 * 10
h = centimeter. 2) v positive = 10 * 10 * 10 = 1000 cubic centimeters v cylinder = s bottom * h = 1000
S bottom = 1000 4 = 250 cm.

Let y be equal to the square of x, and substituting it into the original formula to get y squared minus 2 times the root number 2y plus 1 equals 0, and then the value of y can be obtained from the equation, so that y is equal to the root number 2 plus 1 or the root number 2 minus 1, so the square of x root number 2 plus 1, or equal to the root number 2 minus 1.
