Answer:
Flame test
Explanation:
There are many tests are present to identify the ions. It is very important before going to perform any test you must know all the information bout it.
Flame test:
The metals ions can be detected through the flame test. Different ions gives different colors when heated on flame. Tom perform the flame test following steps should follow:
- Dip a wire loop in the solution of compound which is going to be tested.
- After dipping put the loop of wire on bunsen burner flame.
- Observe the color of flame.
- Record the flame color produce by compound
Colors produce by ions of some metals:
calcium (Ca+2) orange-red
lithium (Li+) red
potassium (K+) Lilac
copper ( Cu+2) blue-green
sodium (Na+) yellow
Answer:
I was having trouble with this question idk the answer
Explanation:
Answer:
It becomes a positive ion and its radius decreases
Explanation:
As per the Octet rule, Barium has 2 electrons in its outermost shell. When it loses the two electron it gains two positive charge i.e Ba2+. As the barium loses the two electron from its outermost shell, the outermost shell becomes vacant and thus is no more considered as a part of atomic geometry of the barium atom and since the outermost shell is considered negligible the radius of barium atom reduces automatically.
