Day 6 - Isotopic Symbol and Ionic Notation

Question 1

This is the code for a chemical element and consists of 1 or 2 letters either greek or latin

Answer 1

Symbol

Question 2

How many letters in a symbol is assigned if its temporary or to newly synthesized or not yet synthesized element?

Answer 2

3 letters

Question 3

Uno is for what?

Answer 3

It is for a temporary symbol of hassium

Question 4

What are the components in an element of the periodic table

Answer 4

Nucleon Number or Mass Number
Proton Number or Atomic Number
Ionization
Number of Atoms
Radical indicated by a dot

Question 5

It is the left superscript and it may have “m” or “f” which is stand for nuclear isomer. Atomic plus Neutron

Answer 5

Nucleon Number

Question 6

It is in the left subscript which indicates the change of the number of nucleons in a nuclear reaction or the number of Protons

Answer 6

Proton Number or Atomic Number

Question 7

It is found at the right superscript and it indicates the charge of an element

Answer 7

Ionization

Question 8

It is at the right subscript and it is usually 1 because in an element there is 1 atom of that kind

Answer 8

Number of Atoms

Question 9

It is often omitted and it is deducible from the charge. It is true for non-bonded covalent

Answer 9

Radical Indicated by a dot

Question 10

What is the postulate of Dalton’s Atomic Theory

Answer 10

All atoms of an element are identical but not identical in all aspects
1. Mass of atom
2. Atoms of the same element has different Mass (Isotope)
3. Isotope - diff. number of neurons and it is identified by a mass number
4. Atoms gain charges
Ion - lose or gain an atom
Neutral - no. of electrons = No. of protons

Question 11

It is a neutral element if?

Answer 11

Electrons = Protons

Question 12

It is when electrons are removed from a neutral charge

Answer 12

Cation (+)

Question 13

It is when an element gains an electron

Answer 13

Anion (-)
