Atoms that are the same kind is called?
Isotopes - atoms with the same atomic number, number of protons and number of electrons
List the nameof each element that appears in the formula and give the number of atoms of each element present. HOOCC6H4OOCCH3?
Hydrogen - 8 Oxygen - 4 Carbon - 9 So, shorthand formula is C9H8O4 = aspirin
Do many elements have the same type of atom?
By definition, an element is a substance with only one type of atom. So no, each element has its own type of atom.
How many atoms are in ununseptium?
Ununseptium is a synthetic element with the atomic number 117. Since it is an element, it is made up of individual atoms. However, the stability and existence of ununseptium have not been confirmed, so it is challenging to determine the exact number of atoms in a sample.
Is it true that atoms of the same element have the same number of protons?
Yes, it is true that atoms of the same element have the same number of protons. The number of protons in an atom determines the element it is, so if two atoms have the same number of protons, they are the same element.
Which has the greatest number of atoms- 3.5 grams of helium or 3.5 grams of lithium?
3.5 grams of lithium would have a greater number of atoms because lithium is heavier than helium. Each element has a different atomic mass, so the same weight of each element will contain a different number of atoms.
How do atoms define or determine elements?
Each element is different so for a certain element to be define/determined it has different atoms to make it up so no other element has the same atoms

What information do prefixes in the name of a binary molecular compound tell you about the composition of the compound?
Prefixes in the name of a binary molecular compound indicate the number of atoms of each element present in the compound. The prefixes specify the quantity of each element in the compound, such as mono- for one, di- for two, tri- for three, and so on.
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
How is atomic number used to tell one element from another?
The atomic number of an element stands for the number of protons in the unique atom of the element. The atomic number also is the same as the number of electrons. The atoms in each element differ from atoms in other elements by virtue of the number of positively charged protons in the atomic nucleus and the corresponding number of negatively charged electrons. The number of protons (or electrons) is the atomic number of the element. The atomic number ranges from 1 for Hydrogen to 92 for Uranium and then beyond through the transuranic elements created in laboratory conditions.
Do many elements have the same type of atom?
By definition, an element is a substance with only one type of atom. So no, each element has its own type of atom.
How can I tell if a chemical reaction is balanced or not balanced?
If the equation has the same number of each type of atom on both sides of the arrow, it is balanced. If the number of atoms on each side of the arrow is not the same, the equation is not balanced. For example, in the equation H2 + O2 -->H2O, there are two hydrogen atoms and two oxygen atoms on the left, and two hydrogen atoms and one oxygen atom on the right. Therefore, the equation is not balanced. However, in the equation 2H2 + O2 -->2H2O, there are four hydrogen atoms and two oxygen atoms on the left and four hydrogen atoms and two oxygen atoms on the right, so the equation is balanced.
How do you determine the number of atoms and elements in a chemical form?
Look at the subscripted number to the right each element's symbol. That is how many atoms of that element are in one formula unit. If no number appears next to the chemical symbol, then the number of atoms is 1. The total number of atoms is the sum of the number of atoms of each element. For example, the formula for sulfuric acid is H2SO4, a compound of the three elements hydrogen (H), sulfur (S), and Oxygen (O). Hydrogen's subscript is 2, oxygen's is 4, and Sulfur does not have a subscript. So 1 molecule of sulfuric acid contains 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms, for a total of 7.
How do you know if two atoms are from the same element?
Two atoms are from the same element if they have the same number of protons in their nuclei. This is the defining characteristic that determines an element's identity. For example, all carbon atoms have 6 protons, so any two atoms with 6 protons are considered to be the same element, carbon.
What is molecular formulae?
The molecular formula of a compound is the number of atoms of each element in one molecule. So in water (H2O), one molecule of water has 2 Hydrogen atoms and one oxygen.
