Groups

Same number of valence electrons

Li, Na, K

Explanation:

If the periodic table is not color coded, the groups of elements gives the arrangement of atoms with the same chemical properties.

All elements that are in the same group have the same chemical properties.

Periodic table groups are also called family. They are the vertical columns on the periodic table.

Elements that same number of electrons in outermost shell have the same chemical properties.

The outermost shell is called the valence shell of an atom.

They are the shell containing the most loosely held electrons. Group 1 has just one electron in their outermost shell.

Li Na k group 1

F Cl Br group 7

The length of a certain wire is kept same while its radius is doubled. what is the new resistivity of this wire?

anastassius [24]

The text does not specify whether the resistance R of the wire must be kept the same or not: here I assume R must be kept the same.

The relationship between the resistance and the resistivity of a wire is
$\rho = \frac{AR}{L}$
where
$\rho$ is the resistivity
A is the cross-sectional area
R is the resistance
L is the wire length

the cross-sectional area is given by
$A=\pi r^2$
where r is the radius of the wire. Substituting in the previous equation ,we find
$\rho = \frac{\pi r^2 R}{L}$

For the new wire, the length L is kept the same (L'=L) while the radius is doubled (r'=2r), so the new resistivity is
$\rho' = \frac{\pi r'^2 R}{L'}= \frac{\pi (2r)^2 R}{L}=4 \frac{\pi r^2 R}{L} = 4 \rho$
Therefore, the new resistivity must be 4 times the original one.

if the resistance of a car headlight is 15 ohm and the current through it is 0.60, what is the voltage across the headlight?

Strike441 [17]

Answer:

9 volts (assuming 0.60 is in Amperes)

Explanation:

Recall that Ohms law can be expressed as

V = IR, where

V = voltage,

I = current (given as 0.6. I'm going to assume that the units is Amperes because it is not given)

R = resistance (given as 15 ohm)

substituting the above values into the formula

V = IR

V = (0.6)(15)

V = 9 Volts

How can you determine the rate of a chemical reaction?

DanielleElmas [232]

Take a look at a simple reaction like the one below:

In this reaction some reactant A is turned into some product B. The rate of reaction can be represented by a decrease in concentration of A over time or as the increase of B over time. This is written:
