Where are non-metals in the periodic table?
In general along the period from left to right the non metallic property of elements decreases... also down the period the metallic property increases in general... Hence, we mostly find the non metals in the p-block, especially in the upper periods... Halogens, Chalcogens , Pnicogens , are almost all non metals with a few exception (metalloids like Bismuth)...
Does electropositivity increases or decreases as you move left to right across a period on the periodic table?
Electropositivity decreases along a period. The metallic character also decreases.
Where are non metals in the periodic table?
Non metals are found on the right hand side of the table. If there is a dark, stair-step looking line on your table (not all have it), they will be to the right of that line.
What happens to the reactivity of a nonmetal when you move from left to right in a group?
The reactivity of a non metal decreases as you move down a group. This is because the size of the atomic radius increases and when the distance to the nucleus increases, the force of attraction decreases. Electrons are not pulled as strongly to larger atoms, and so larger atoms are not as reactive.
What type of data does CIEN show?
The type of data CIEN shows is the following, it shows how the stock changes along time. Whether the price of the stock increases or decreases with selectable time periods.
Who is responsible for the weeds along the railroad tracks and along N.M. highways?
Whoever owns the property. If it's railroad property, the railroad is responsible. If it is highway property, it can be the state's responsibility.
What is an element that is not shiny and does not conduct heat and electricity well?
An example of an element that is not shiny and does not conduct heat and electricity well is sulfur. Sulfur is a brittle, non-metallic element that typically appears as a yellow solid. It is poor in terms of electrical and thermal conductivity, making it a good insulator. This property, along with its dull appearance, distinguishes sulfur from many metallic elements.
Why is Tin metallic in nature in spite of being in Group 4 in the periodic table?
Tin is metallic because the shielding of electrons is so much that the electrostatic force is weak and so Tin is metallic. Moreover as we move from right to left in a periodic table and top to bottom along the group the metallic character increases. Hence Sn is metallic.
What trend does the atomic radius along a period on the periodic table?
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
Are metallic and glassy two types of cleavage?
No, metallic and glassy are not types of cleavage. Metallic refers to a type of luster in minerals, while glassy describes the appearance of a mineral's surface. Cleavage refers to the way a mineral breaks along planes of weakness.
What is the trend found in Period 3 on the Periodic Table as the elements increase in atomic number?
1-Atomic size = decreases 2-Ioniztion energy = increases 3-Electronegativity = increases (except Argon) 4-Metallic character = decreases 5-Melting point = first increases then decreases
What trend does electronegative following down the periodic table?
Electronegativity decreases along a period. This is because atomic radius increases increases, hence nuclear charge decreases.
