Positive Temperature Coefficient).......by vamsi
Positive. It wants to lose two electrons to get to the electron configuration of its nearest noble gas, Ne (Neon).
Boron gains noble gas configuration by losing 3 electrons. So it forms positive ions.
There are four electrons in a Beryllium atom. Hence the mono positive ion has only three electrons. Therefore the electron configuration is 1s2 2s1.
A cation is a positive ion. To get 2 positive charges the atom would need to lose 2 electrons. As its configuration is 2,8,2, this is what it is likely to do when it reacts as the resulting ion has an inert gas structure.
positive
positive
yes
negative 'temperature coefficient of reactivity'
ntc: negative temperature coefficient ptc: positive temperature coefficient
When the coefficient is positive, the line goes up and to the right.

no, false
positive
Has a positive gradient (in a y=mx+c graph)
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
1) Positive Temperature Coefficient 2) Positive Train Control.
