- Use + (plus sign) in superscripts or in the baseline.
- Use – (minus sign) in superscripts only.

How do you write electrons in mastering chemistry?
Enter a minus sign (-) after the caret (for superscript). For example, to represent a cobalt atom with two extra electrons (Co2-), type Co^ (2-). For an ionic molecule or formula: The superscript indicating the charge must come at the very END of the molecular formula.
How do you enter subscripts in mastering chemistry?
- For a single-digit subscript: Follow the underscore with the number. For example, to represent H2 type H_2.
- For two or more digits in a subscript: Follow the underscore with the digits in parentheses, such as _(110).

How do you subscript in mastering physics?
Mastering uses string matching to grade such answers. Parentheses to distinguish some subscripts and exponents: Add parentheses around a subscript or exponent when it’s immediately followed by another subscript or exponent that should NOT be applied to the earlier subscript or exponent.
How do you write scientific notation in Pearson?
How do you type the atomic symbol?
How do you learn electron configuration?
How do you calculate electron arrangement?
The electron arrangement of an atom can be worked out from its atomic number. For example, the atomic number of sodium is 11. Sodium atoms have 11 protons and so 11 electrons. This electron arrangement can be written as 2.8.
What is 1s 2s 2p 3s 3p?
1s 2s 2p 3s 3p represents the electron orbital energy levels.
How many electrons are in the 4th shell?
The fourth shell holds 32 electrons; 2 in a 4s orbital; 6 in three 4p orbitals; 10 in five 4d orbitals; and 14 in seven 4f orbitals. The exact arrangement of electrons in an atom’s shells and subshells is the atom’s electron configuration. It can be predicted by applying three rules.
What are the three rules for writing the electron configuration of elements?
What are the three rules for writing the electron configurations of elements? Three rules—the aufbau principle, the Pauli exclusion principle, and Hund’s rule—tell you how to find the electron configurations of atoms.

How do you write CH4 in Word?
There are some steps to be followed to write a chemical equation in MS Word and the steps vary for android and computer. “CH4 + O2 -> CO2 + H2O”. Type CH4 and click “Shift + left arrow” it selects “4” and press “Ctrl ++”, it subscript(Print below the line)the letter you select. Similarly type O2, CO2, and H2O.
How do you find electrons in isotope notation?
To find the number of electrons, add the opposite of the charge imbalance to the number of protons. For example, if an isotope has a -3 charge, as with phosphorus (atomic number 15), then the number of electrons is three greater than the number of protons.
How do you write isotope notation?
How do you write elements?
Instead, write the element name or symbol, followed by the number of protons plus neutrons. For example, helium-3 or He-3 is the same as writing 3He or 31He, the most common isotope of helium, which has two protons and one neutron.
