Iodine itself is neither inherently positive nor negative; it is a chemical element essential for human health, particularly in thyroid function. However, in certain contexts, such as its use in disinfectants or as a contrast agent in medical imaging, iodine can have positive effects. Conversely, excessive iodine intake can lead to negative health consequences. Overall, its impact depends on the context and dosage.
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Negative * positive = negative Positive * positive = positive Negative * negative = positive
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
positive and a positive is a positive negative and a negative is a positive to answer your question: positive and a negative is a negative.
If iodine is not applied, both the gram-positive and gram-negative stains will appear to be gram-negative. The iodine acts as a mordant that helps to fix the crystal violet stain in the gram-positive bacteria, making them appear purple. Without iodine, the crystal violet stain can be easily washed out of both gram-positive and gram-negative bacteria, resulting in a pink or red color.
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66

A negative iodine test for starch indicates that the starch has been broken down by amylase into simpler sugars, such as maltose or glucose, that do not react with iodine. Therefore, the absence of a starch-iodine complex formation suggests that amylase has successfully degraded the starch substrate.
Sodium iodide is composed of sodium (Na) atoms and iodine (I) atoms. Sodium contributes the positive charge, while iodine provides the negative charge.
Iodine typically gains an electron to form a -1 ion.
Positive + Negative = Negative Negative + Negative = Positive Positive + Positive = Positive Negative + Positive = Negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
The rules for the sign (positive or negative) of the result of a multiplication is the same as division. For multiplication: Positive * Positive --> Positive Positive * Negative --> Negative Negative * Positive --> Negative Negative * Negative --> Positive For division: Positive / Positive --> Positive Positive / Negative --> Negative Negative / Positive --> Negative Negative / Negative --> Positive
Yes. Negative/negative = positive Postive/Positive = positive Negative/Positive - negative
Negative * positive = negative Positive * positive = positive Negative * negative = positive
A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.
