What else can I help you with?
The nuclei of all atoms of a given element always have the same number of what?
The nuclei of all atoms of a given element always have the same number of protons. This number is unique to each element and is known as the element's atomic number.
Which element is the most likely to be reduced?
The element that is most likely to be reduced is the element that has the highest reduction potential (E°) in a given redox reaction. The element with a more positive reduction potential is more likely to undergo reduction.
How do you know when to solve for a empirical formula?
You should solve for an empirical formula when you are given the percent composition of elements in a compound or when you have the molar mass of the compound but not the molecular formula. The empirical formula provides the simplest whole-number ratio of atoms in a compound.
What has the mass number of 41?
The mass number of an element is the total number of protons and neutrons in its nucleus. Given that the atomic number (number of protons) uniquely identifies an element, knowing just the mass number of 41 is insufficient to determine the specific element without additional information.
What does an element's molar mass tell you about the element?
An element's molar mass represents the mass of one mole of that element in grams. It tells you the average atomic mass of the element, which is the sum of the protons and neutrons in the nucleus of its atoms. Molar mass helps in determining the amount of substance in moles when given the mass of the sample.
What type of food should you give someone that has old jaundice?
A person that old jaundice can be given just about anything they want to eat. Food does not effect jaundice.
Is COPD is a disease that is a combination of lung cancer and bronchitis?
Chronic Obstructive Pulmonary Disease (COPD)
What element is given by gallium?
The element of gallium is Ga3.
How do the isotopes of given element differ from one another?
isotopes of a given element differ in the number of neutrons they have.
Why did scandium get its symbol?
Every element is given a symbol and so, scandium being an element, was also given one.
Can someone with COPD be given an influenza vaccination?
Yes. Having Chronic Obstructive Pulmonary Disease (COPD) is not a contraindication to receiving an influenza vaccination.
What is the atomic number in a given element equivalent to?
The atomic number in a given element is equivalent to the number of protons in the element.
What device analyzes the light given off when an element is burned?
A spectrometer analyzes the light given off when an element is burned.
What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
What is the name given to the side element in a casement window?
The side element is called a vent.
What information is given by the group number of an element?
Indications about the general chemical properties of this element.
How can you say given element is more oxidative?
no
