What is the periodic table

A tool to organize the elements

Where are electrons found in the atom

At different distances from the nucleus

What was the purpose of the periodic table

The periodic table of the elements organizes chemical knowledge about the various elements in a way that enables us to understand why different elements have the chemical properties that they have.

What are the rows of the periodic table called

Rows of the periodic table are called periods.

Which type of volcano consists of layers of lava flows and pyroclastic material

A composite cone is the type of volcano that consists of layers of lava flows and pyroclastic material. A stratovolcano is an example of a composite cone.

Are there buildings taller than 100 stories

There are lots of buildings higher than 100 stories. Many skyscrapers are taller.

Which of the following elements is an alkaline earth metal

The alkaline earth metals are beryllium, magnesium, calcium, strontium, barium, and radium.

What are elements in the tall columns of the periodic table called

Representative elements

What do the letters in the boxes of the periodic table represent

The letters are a one- or two-letter symbol assigned to each element

Which electrons are the valence electrons of the atom

The correct answer is: The electrons farthest away from the nucleus...

How does the periodic table indicate the number of valence electrons an element has

By the group number of the A columns.....go apex :D

Which elements occupy the same group in the periodic table

Elements that share the same column.

How many valence electrons does S-32 have

6

Why do all the elements in Group 16 share similar properties

They all have the same number of valence electrons

How did quantum mechanics change your understanding of atoms

In quantum mechanics, electrons exist in a cloud-shaped area outside the nucleus.

I found the concepts mind-blowing and it took me a couple of weeks to get comfortable with it.

What is a characteristic of the lanthanides

They are silvery metals that conduct electricity

What does the group number of A elements tell about valence electrons

All elements in the same A group will have the same number of valence electrons.

Which Group is in the second column of the periodic table

Spread the weight of the ship over a greater volume

What period is Zn (zinc) in

12

What did Henry Moseley determine that contribute to understanding the atom

Moseley proposed formulas of calculus justifying the atomic number of the chemical elements in the periodic table and their arrangement in the table.

What do all the elements in one row of the periodic table have in common

They all have the same number of core electrons

Which describes green design
