The atomic number of beryllium (Be) is 4, and the atomic number of barium (Ba) is 56. Which comparison is best supported by this

information?
A: They are in the same group because they have similar atomic masses, but they are in different periods because they have different chemical properties.
B: They are in the same group because they have similar chemical properties, but they are in different periods because they have very different atomic numbers.
C: They are in the same group because their atomic numbers are each multiples of four, but they are in different periods because they have different chemical properties.
D: They are in the same group because they have similar atomic masses, but they are in different periods because they have very different atomic numbers.

The answer is:

B)They are in the same group because they have similar chemical properties, but they are in different periods because they have very different atomic numbers.

The explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

A period is a horizontal row of elements on the periodic table. For example, the elements sodium ( Na ) and magnesium ( Mg ) are both in period 3. The elements astatine ( At ) and radon ( Rn ) are both in period 6.

Solve the equation. 5x-5=10x+2
Veronika [31]

Answer:

x = - 1.4

Explanation:

-5=10x+2-5x     (subtract 5x from both sides)

-5=5x+2     (simplify)

-5-2=5x     (subtract 2 from both sides)

-7=5x      (simplify)

x=-7/5     (divide both sides by 5)

x=-1.4    (simplify)

i would really appreciate getting a brainliest. anyways i hope this helped and have a great rest of your day/night!! :)

Two pulses are moving along a string one pulse is moving to the right and the second is moving to the left. Both pulses reach po
MatroZZZ [7]

Answer:

Constructive interference

Explanation:

- This is an example of a standing wave produced when two ends of a string are oscillated in the same plane. The displacement of of point on two ends oscillates vertically.

- We are given that two pulses move along the string each coming towards each other and meet at a common point ( P ).

- Each pulse have their own magnitude or displacement in the vertical plane. If the pulses are to meet at a common point at the same instant, then they interfere with each other constructively.

- Where constructive interference of two pulses is the addition of magnitudes of induvidual pulses and form a single puls of the constructed magnitude.

    magnitude ( New pulse ) = magnitude (Pulse 1) + magnitude (Pulse 2)
