What is the total volume of the nucleus of an atom is?
This will depend on the element, but in general, it can be considered to be approximately 7.2×10−45 m3 to about 1.7x10^-42m3.
Mass number of elements?
The mass number of an element is the total number of protons and neutrons in its nucleus. It is used to identify different isotopes of an element based on the varying number of neutrons. The mass number is usually represented as a superscript to the left of the element's symbol.
What is an atom's mass number?
An atom's mass number is the total number of protons and neutrons in its nucleus. It is used to identify isotopes of an element since isotopes of the same element have the same number of protons but different numbers of neutrons.
Explain how to count atoms when coefficient are present?
To count atoms when coefficients are present in a chemical equation, first identify the coefficients, which indicate the number of molecules or moles of a substance. Multiply the coefficient by the subscript of each element in the compound to determine the total number of atoms for that element. If there are no subscripts, assume the subscript is 1. Finally, sum the total counts for each element across all compounds in the equation.
How do you count atoms worksheet?
To count atoms on a worksheet, first identify the chemical formulas present. For each element in the formula, note the subscript that follows it, which indicates the number of atoms of that element. If there is no subscript, it means there is one atom of that element. For compounds with parentheses, multiply the subscript outside the parentheses by the subscripts inside to find the total number of atoms for each element.
What element has 10 electrons when it form an anion with a 2 negative charge.?
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
How may elements does a diatomic molecules have?
we can identify the element having diatomic by finding out the valency of that element. i think it helps you.
What is debt-to-equity ratio?
Total liabilities divided by total assets.This ratio is used to identify the financial leverage of the company i.e. to identify the degree to which the firm's activities are funded by the owners money versus the money borrowed from creditors.The higher a company's degree of leverage, the more the company is considered risky.Formula:DER = Net Debt / Equity
What element has a total of electrons?
Phosphorous
How many element combos are there?
The total number of element combinations depends on the number of elements that are being combined. For example, if you are combining 2 elements, there would be a total of 2 combinations (element 1 + element 2). If you are combining 3 elements, there would be a total of 6 combinations (element 1 + element 2, element 1 + element 3, element 2 + element 3). The formula to calculate the number of combinations is n(n-1)/2, where n is the number of elements being combined.
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
Atomic number determines the identity of an element. It represents the number of protons in an atom's nucleus, which is unique to each element. Mass number refers to the total number of protons and neutrons in an atom's nucleus, while atomic mass is the average mass of an element's isotopes. Overall charge is determined by the number of protons and electrons in an atom, but it does not uniquely identify the element.
What element has a total of 20 electrons?
Calcium
