There will be 3 spiders and 4 ants. 3 spiders x 8 legs = 24 legs. 4 ants x 6 legs = 24 legs.
The valency of first four main group elements is equal to their group numbers but elements from Group 5 to 8 have two valencies one equal to group number and second is obtained by subtracting group number from 8.
When you have finished dividing, the divisor (the number you divided BY) and thequotient (the answer you got) together, are both of those numbers, either way.Either of them can be the number of equal groups, and then the other one is thenumber in each group.
equal. depends on the age group.
The numbers on the left side of the table are the period numbers and on the top are the group numbers.
By adding up all the numbers in the group and dividing by the number of numbers in the group.
The range of a group of numbers is equal to the difference between the smallest and the largest numbers in the group.
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
To get the range of a group of numbers you subtract the smaller number from the larger one The mean is the "average" for a group of numbers to get the mean you add all the numbers together. Then divide that number by the number in the group.
The middle number out of a group of numbers.
He has 2 valence electrons. Look on a periodic table. It will show He only has 2 protons and the number of protons and electrons is equal. It is an exception to the rule of group numbers corresponding to valence numbers.
Average of the numbers in a group =(the sum of all the numbers in the group) divided by (the number of numbers in the group)
