Answer: it’s a I believe
Explanation: protons are smaller then atoms which means they have less mass
Answer:
H-BI,H-Se,H-S,H-I,H-Br
Explanation:
One thing that must be kept in mind is that atomic size increases down the group and decreases across the period. The bond lengths of species are influenced by the relative sizes of atoms or ions present in the bond.
The bonds in the answer have been arranged on basis of their decreasing atomic size because the greater the atomic size of the atoms, the greater the bond length and vice versa.
Answer:
the atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope
Explanation:
Average atomic mass = f1M1 + f2M2 + … + fnMn where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope. The average atomic mass of an element can be found on the periodic table, typically under the elemental symbol.
The average annual precipitation has been calculated by dividing the sum of average rainfall to the number of years. Thus, the given statement is true.
Precipitation has been given as the amount of water in the atmosphere that has been to fall off on the earth.
<h3 /><h3>Average Annual Precipitation</h3>
The average has been defined as the mid-value for the number readings. The average precipitation has been the approximate fall of water on the earth in the specified period.
The average annual precipitation has been calculated with the ratio of the sum of the average rainfall in the number of years to the total number of years. Thus, the given statement is true.
