Periodic Table
The Periodic Table is a tabular arrangement of the elements in increasing order oftheir atomic numbers, so that elements with similar properties are in the same column. There are 18 columns, called groups, and seven rows, which are called periods, in the modern periodic table. Questions about the Periodic Table: its history and creation, trends, groups/families, and periods are asked in our Periodic Table category.

Zirconium(Zr) has an atomic number of 40. It is in Group 4 and Period 5.
Assuming the man stands at the edge of the table, he can stand up to 1/3 of the table's length from the right edge, which would be around 19 inches from the edge for a 56-inch table. However, the distribution of weight and stability of the table base can also affect this distance.
What does CO2 mean on the periodic table?
CO2 Stands for Carbon Dioxide
- - - - -
CO2 is a compound, so it wouldn't be on the periodic table in the first place.
What elements are on the Dalton's table and also on the modern periodic table?
Both John Dalton's table and the modern periodic table contain elements like hydrogen, oxygen, carbon, and nitrogen that are essential building blocks of matter. However, Dalton's table had elements grouped by atomic weight, while the modern periodic table arranges elements by atomic number.
What is the group trend for the ionization energy for the alkali metals?
As you go down the group (any group), ionization energy decreases. So in terms of ionization energy, for the alkali metals,
Lithium > Sodium > Potassium > Rubidium > Caesium > Francium
Which atomic property is different in each isotope of an element?
The number of neutrons in the nucleus is different in each isotope of an element. Isotopes of an element have the same number of protons (atomic number) but different numbers of neutrons, leading to variations in atomic mass.
Who was the woman who made an element on the periodic table?
Marie Curie was the woman who discovered the elements polonium and radium, both of which are on the periodic table. She was a pioneering physicist and chemist who conducted groundbreaking research on radioactivity.
Is nitrogen an element that helps plants grow?
Yes, nitrogen is an essential nutrient for plant growth. It is a key component of chlorophyll, which is necessary for photosynthesis. Plants can absorb nitrogen from the soil in the form of nitrates or ammonium ions to support their growth and development.
Alkali metals
Nonmetals
Halogens
Why cathode ray are not electro-magnetic waves?
A cathode ray is a stream of electrons, not a stream of photons like the electromagnetic wave. It's a different type of particle. The electrons don't move at light speed in a vacuum; also, they are electrically charged.
How many elemets were in the periodic tabel in 1834?
There were around 52 known elements in the periodic table in 1834. The periodic table was still in its early stages of development during this time, and many elements were discovered and added to the table in the years that followed.
What is the atomic number for an abundant element with mass number of 12?
The element with a mass number of 12 is carbon. Carbon has an atomic number of 6.
What does N2O mean in the periodic table?
N2O refers to nitrous oxide, a chemical compound made up of nitrogen (N) and oxygen (O). Nitrous oxide is a greenhouse gas and is also commonly known as laughing gas due to its anesthetic properties when inhaled.
The symbol "W" for tungsten comes from its German name, which is "Wolfram". In the 18th century, tungsten was often referred to as "wolframite", and the abbreviation "W" was derived from its mineral name.
What does silver ore look like in its natural state?
Silver ore in its natural state typically appears as a metallic mineral with a silver-gray coloration and a shiny, metallic luster. It can often be found in veins or deposits embedded within rocks or mineral formations.
Do alloys help to eliminate undesired elements in a metal?
Alloys can help to eliminate undesired elements in a metal by diluting the concentration of the undesired elements and redistributing them throughout the material. Some elements in the alloy may also react with the undesired elements to form compounds that can be removed during the manufacturing process.
How do you draw an atomic model for the element Cu?
JUST follow this instruction
Instructions- 1
Glue the 29 red and 35 blue beads or balls together in a clump or onto a large Styrofoam ball. Make the placement random. Do not glue all the red or all the blue balls to each other.
- 2
Slide two of the yellow beads on to the shortest wire. Glue them to the wire by placing a dab of glue inside each bead. Hold each bead while it dries. Make sure the beads are spaced equally on the wire.

Slide eight of the yellow beads onto the next shortest wire. Glue them to the wire by placing a dab of glue inside each bead. Hold each bead while it dries. Make sure the beads are spaced equally on the wire.
- 4
Slide eighteen of the yellow beads on to the next second longest wire. Glue them to the wire by placing a dab of glue inside each bead. Hold the bead while it dries. Make sure the beads are spaced equally on the wire.
- 5
Slide the last yellow bead onto the longest wire. Glue it to the wire by placing a dab of glue inside the bead. Hold the bead while it dries.
- 6
Connect the ends of each wire with tape or glue. You should now have four rings.
- 7
Tie one end of the string onto the smallest circle. Tie the other end to the next smallest circle. Leave enough space that the electron beads do not touch.
- 8
Repeat step 7 for the each of the circles until all of the circles are tied together.
- 9
Tie one end of a string onto the smallest ring. Tie the other end around the nucleus or tape or glue it to the top of the nucleus.

Why is the periodic table related to medicine?
The periodic table is related to medicine because it helps in understanding the chemical elements present in medications and the human body. Elements like oxygen, carbon, hydrogen, and nitrogen are essential for life and play a crucial role in drug development and biological processes within the body. Additionally, the study of elements and their interactions is important in pharmacology to create effective and safe pharmaceuticals.
Carbon is in period 2 on the periodic table of the elements.
Is aluminium oxide mixture element or compound?
Yes. Aluminum nitrate is a compound with the formula Al(NO3)3
What is the valency of ferrous and ferric ion?
Whether iron is in the ferrous or ferric state depends on the ionic charge of the iron cation, which can either exist in the +2 or +3 oxidation state. Iron is a metal and will therefore take a positive charge. Iron happens to be, more specifically, a transition metal so it can form multiple positive ions. The -ous ending means it is in the lower oxidation state (+2) and the -ic ending means it is in the higher oxidation state (+3).
