Compare and contrast the possession of electrons in ionic and covalent bonds?
In an ionic bond, one atom loses electrons( becomes more positive) and the other gains the electrons ( becomes more negative) what keeps them bonded is the now positive/negative attraction. In covalent bonding, both atoms share the electrons, but are again held together by positive/negative attraction.
How does the density around a partial positive electron atom compare to the density of a partial negative?
The density around a partial positive electron atom is higher compared to a partial negative electron atom. This is because in a partial positive atom, electrons are being pulled towards the nucleus due to the partial positive charge, leading to a higher electron density around the atom. In contrast, in a partial negative electron atom, electrons are being pushed away from the nucleus, leading to a lower density around the atom.
Compare the total amount of energy before and after physical and chemical changes?
In physical changes, the total amount of energy before and after remains the same as no new substances are formed. In chemical changes, there may be a difference in the total amount of energy before and after the reaction due to the formation of new substances and the breaking or forming of chemical bonds.
How would you compare physical and chemical properties and physical and chemical changes?
Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color or density. Chemical properties describe how a substance interacts with other substances, like its ability to rust or burn. Physical changes alter a substance's appearance or state without changing its chemical composition, while chemical changes result in the formation of new substances with different chemical properties.
Compare and contrast ions with isotopes.?
Ions are atoms that have gained or lost electrons, giving them a positive or negative charge, while isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Ions can be formed from any element by gaining or losing electrons, whereas isotopes occur naturally and are specific to a particular element.
How Compare the formation of positive ions with the formation of negative ions in terms of energy changes?
The formation of positive ions typically involves the loss of one or more electrons from an atom, which requires energy input to overcome the attraction between the electrons and the nucleus; this energy is called ionization energy. In contrast, the formation of negative ions occurs when an atom gains one or more electrons, a process that usually releases energy, known as electron affinity, as the added electron is attracted to the nucleus. Thus, while the formation of positive ions is endothermic (requiring energy), the formation of negative ions is exothermic (releasing energy).
How does the sign of the product of the positive and a negative number compare withe the sign of the sum of a positive and a negative number?
The product of a positive and negative number is always negative The sum of a positive and negative number depends on which one is larger; subtract the two numbers and take the sign of the larger
Is the word comparative a negative connotation?
No, it simply means to compare two things. They could be positive or negative.
How do radii of positive and negative ions compare with atoms of the same element?
Small positive ion, Mid elemental atom, Large negative ion.
How can you compare a positive integer to a negative integer?
All positive integers are all greater than negative integers.
How does the quotient between 2 negative numbers compare to the value of the original 2 integers?
The quotient of two negative numbers is positive. So, when dividing two negative numbers, the result will be positive.
Compare and contrast The Electric Field Around The Negative Charge And The Electric Field Around A Positive Charge?
A negative charge is caused by a excess of electrons and a positive charge by their lack.
Compare an anode and a cathode?
The Anode (+) is what you connect the positive voltage to The Cathode (-) is what you connect the negative voltage to.
How does the amount of positive charge on a proton compare with the amount of negative charge on a electron?
equal but opposite
When adding integers how can you tell whether the sum will be positive negative or zero without really adding?
To determine whether the sum of integers will be positive, negative, or zero without actually adding, you can compare the counts of positive and negative integers. If there are more positive integers than negative ones, the sum will be positive. Conversely, if there are more negative integers, the sum will be negative. If the counts are equal and they are of the same absolute value, the sum will be zero.
When you add a positive number and a negative number how do you determine the sign of the answer?
To determine the sign of the sum when adding a positive number and a negative number, compare their absolute values. If the positive number has a greater absolute value, the result will be positive; if the negative number has a greater absolute value, the result will be negative. If the absolute values are equal, the result will be zero.
How can we tell without calculating whether the sum of a positive number and a negative number will be positivenegative or zero?
To determine the sum of a positive number and a negative number without calculating, we can compare their absolute values. If the absolute value of the negative number is less than the positive number, the result will be positive. If the absolute value of the negative number is greater than the positive number, the result will be negative. If they are equal, the sum will be zero.
