Halogens are in the group 17 of the Periodic Table of Mendeleev.
What else can I help you with?
Does the stratosphere contains the ozone layer?
Yes, the stratosphere contains the ozone layer. The ozone layer is a region of the stratosphere that contains a high concentration of ozone molecules, which help to absorb and block harmful ultraviolet radiation from the sun.
Are there more new elements left to be discovered?
It is possible that there are still new elements left to be discovered, especially in the superheavy region of the periodic table. Scientists continue to search for new elements by creating them in laboratories through nuclear reactions. However, the discovery of new elements is a challenging and complex process.
What is a space that contains few or no molecules?
A vacuum is a space that contains few or no molecules. It is a region devoid of matter, making it a low-pressure environment. Vacuums are commonly used in science and technology for various applications such as in vacuum chambers or vacuum cleaners.
What is the coding region in DNA transcription?
The coding region in DNA transcription is called the gene. It contains the specific sequence of nucleotides that encode for a protein or functional RNA molecule. During transcription, this coding region is transcribed into a complementary RNA sequence by RNA polymerase.
What elements are found to the right of the zig zag on the peridoc table?
Elements found to the right of the zigzag line on the periodic table are nonmetals. This region includes elements like oxygen, nitrogen, fluorine, and neon. Nonmetals tend to be poor conductors of heat and electricity and are more likely to form negative ions in chemical reactions.
A major region of the periodic table It includes the noble gases the halogen element families and other elements that are non-conductors this region is known as?
nonmetals
Region of the periodic table where most radioactive elements are found?
Group 3 of the periodic table contains many of the radioactive elements.
Which region contains fertile?
Answer to region contains fertile valley
The region that contains the navel is the?
abdomen umbilical
What is the head foot region of a cephalopod?
The “Head-Foot” region contains the mouth and sensory organs as well as the foot, the foot contains organs for locomotion.
Where on the periodic table do the most man-made elements appear?
Most man-made elements appear in the lower rows of the periodic table, specifically in the transuranium (after uranium) region. These elements have atomic numbers higher than 92 and are typically synthesized in laboratories using particle accelerators or nuclear reactors.
Which of the regions shown on the periodic table contains mostly elements that are gases at room temperature?
The region containing mostly elements that are gases at room temperature is the rightmost column, known as the noble gases or Group 18. These elements have full outer electron shells, making them stable and non-reactive, which allows them to exist as gases at room temperature.
What region contains somalia and ethiopia?
"The Horn of Africa"
Which region contains the greatest variety of frogs?
