How does electronegative vary across a periodic?
The electro-negativity of elements increases as you move across a period.
How foes IE vary across a period?
it does
How does the atomic radius vary in a period?
Atomic radius decreases across a period from left to right, except for the noble gases.
How does the valency vary on moving down the group?
The valency does not (or tends not to) vary going up and down a group. It varies going across a period.
What elements are in a bobby pin?
The composition of the coating would vary widely, especially since some of them are coloured. The metallic part of a bobby pin is steel which is mostly composed of the element iron.
Do the chemical symbols for elements vary with different languages and alphabets?
No. The chemical symbols for elements are standard across any language. For example Fe = Iron in English as well as in Chinese or Hebrew.
How does ionization enthalpy vary as you move across the periods vary from left to right?
in a period size decreases from left to right and hence electrons are more tightly held to the nucleus. so electron gain enthalpy increases across a period . down the period size increases and thus in general electron gain enthalpy decreses .
Why does the number of elements from period to period vary?
the number of electrons in each orbital increases, so the number of electrons to form a noble gas configuration in ground state increses.
In a series circuit how does the current differ at different places along that circuit?
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
What physical properties do all four substances share?
Four physical properties shared by the metallic elements are that they are ductile, malleable, have good thermal conductivity, and have a metallic luster. They are also good conductors of electricity.
How do properties of elements change within period?
As you move from left to right across a row (or period) in the periodic table, the following things change: -- atomic size goes down -- electronegativity goes up -- electron affinity goes up See the Web Links and Related Questions links to the left of this answer for more details about why the trends occur and also some important exceptions to these trends.
How does atomic radius vary in group and in period on periodic table?
Down a period the atomic radius increases as the number of shells (or energy levels) increases. Across a period the atomic radius decreases as the effective nuclear charge increases.
