Explanation:
A point charge is a model that represents a charge as acting uniformly on its surroundings. The characteristics of a point charge are as follows :
- Electric field lines are outwards if the charge is positive.
- Electric field lines are inwards if the charge is negative.
- If the distance from the point charge increase, the magnitude of the electric field decreases and vice versa.
Answer:
16400.........................
In order to answer this, we will set up a simple ratio as such:
1 calorie = 4.184 joules
1 kilocalorie = 1000 calories
1 kilocalorie = 4,184 joules
250 kilocalories = x joules
Cross multiplying the second and third equations, we get:
x joules = 4,184 * 250
250 kilocalories are equivalent to 1,046 kJ

You may look at what group they are in
Group
1A=Group 1
2A = Group 2
3A = Group 13
4A= Group 14
5A=Group 15
6A=Group 16
7A=Group 17
The #A tells you how many valence electrons there are by the # before A. Such as Chlorine, which is in 7A, so therefore has 7 valence electrons.
