Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Explanation:
All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
The groups in periodic table are vertical columns in which elements with similar properties and same number of valence electrons are classified together.
What are groups in periodic table ?In periodic table, all elements are classified into different periods and groups. The vertical columns in the table is called groups and the horizontal rows are called periods.
The elements in a group have same number of valence electrons and similar chemical and physical properties. For example lithium and sodium are first group elements and they show similarity in properties.
There are 18 groups and 7 periods in periodic table. The first two groups are pure metals. Groups from 3-12 are called transition metals. 13 to 18 group elements are nonmetals.

Which statement best describes how energy and matter move in a wave?
A
A wave transports matter without transporting energy.
B
A wave transports energy without transporting matter.
C
Both energy and matter are transported by a wave.
The following statement which best describes how energy and
matter move in a wave is both energy and matter are
transported by a wave.
What is a Wave?A wave is a disturbance that travels through space-time which
is accompanied by a transfer of energy.
Wave motion also results in the displacement of matter but in a
very minimal manner which makes the Option C the most
appropriate option.

Explain what the H, 2, and O stand for in H2O.
Answer: H stands for Hydrogen, 2 stand for how many Hydrogens are there, and O stand for Oxygen
Explanation: H stand for Hydrogen because on the periodic table the symbol is a H and same goes for O. As for the 2 is represents how many Hydrogens there are because any number right behind the element will represent the amount of that element.

Describe how the wavelengths of energy is organized on the spectrum
Answer:
The electromagnetic spectrum is a continuum of all electromagnetic waves arranged according to frequency and wavelength. The sun, earth, and other bodies radiate electromagnetic energy of varying wavelengths. ... The spectrum of waves is divided into sections based on wavelength.
Explanation:
hope that helps!....
Answer:
When the frequency increases the wavelength decreases and vice versa. There are different sections: radio waves, micro waves, infrared rays, visible light, ultraviolet waves, x-rays, and gamma waves. You can see colors because of visible light.

1. In your own words, explain the difference between a font and air mass.
2. If the weather was briefly stormy, then changed into colder weather, what type of font most likely came through. Explain
3. How does the water cycle affect weather.
THIS IS WORTH A LOT OF MY GRADE GIVING BONUS POINTS AND BRAINLESS FOR ANSWERS
Answer:
1. An air mass is a body of air with a mostly constant moisture and temperature over a significant altitude. Air masses usually cover up to millions of square kilometers. A front is the boundary where two air masses with different temperature and moisture meet.
2. A cold front most likely came through because briefly stormy weather will be warmer and moister than a cold front would.
3. The water cycle is responsible for the rain, snow, and ice that falls. It also affects the wind, so it will all affect the weather.
