A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable. The letters x, y, and z are common generic symbols used for variables.


Variables are used to store information to be referenced and manipulated in a computer program. They also provide a way of labeling data with a descriptive name, so our programs can be understood more clearly by the reader and ourselves. It is helpful to think of variables as containers that hold information.

Merits of modern periodic table?​
ANEK [815]

Answer:

<h3>Merits of modern periodic table:</h3>
  • The wrong position of some elements like argon, potassium, cobalt and nickel due to atomic weights have been solved by arranging the elements in the order of increasing atomic number without changing their own places.
  • The isotopes of some element have the same atomic numbers. Therefore, they find the same position in periodic table.
  • It separates metals from non-metals.
  • The groups of the table are divided into sub groups A and B due to their dissimilar properties which make the study of elements specific and easier.
  • The representative and transition elements have been separated.

Hope this helps...

Good luck on your assignment...

What conclusion can you make about electrons and the periodic table?
kogti [31]

Answer:

The number of valence electrons can be known from the group that the element is in (except the lanthanides, actinides and groups 3-12).

Explanation:

Group 1 has 1 valence electron. Group 2 has 2 valence electrons. Group 13 has 3 valence electrons. Group 14 has 4, group 15 has 5, group 16 has 6, group 17 has 7, and group 18 has 8.

Group 18 are the noble gases which are stable.

Group 17 are the halogens and react well with the alkali metals.
