True or false- all atoms of the same element have the same atomic number?
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
Not all of Daltons rules were completely true as scientists later learned Matter is made of atoms and different elements are made of different atoms But not all atoms of a particular element are?
Dalton's atomic theory proposed that all atoms of a particular element are identical, which we now know is not entirely true. Isotopes are atoms of the same element with different numbers of neutrons, leading to variations in atomic mass. This discovery challenged Dalton's rule of identical atoms for a given element.
The element iodine is a halogen True or false?
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
True or False an atom is the smallest part of a compound that may still be identified as the compound?
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
Is it true or false places in the same hemisphere have the same seasons?
False. Places in the same hemisphere can have different seasons due to factors such as distance from the equator, elevation, and proximity to large bodies of water. These factors can influence the climate and result in variations in the timing and intensity of seasons within the same hemisphere.
an element is a substance composed of atoms that all have the same number of protons.True or false?
True apex
Atoms of different elements have different number of protons true or false?
No atom has the same number of protons as another atom, unless both atoms are atoms of the same chemical element.
The number of atoms in a mole of an element depends on what the element is. true or false?
True. The number of atoms in a mole of an element is determined by Avogadro's number, which is a constant (6.022 x 10^23) regardless of the element being considered. Each element's molar mass in grams is equal to one mole of that element's atoms.
An element is a substance composed of atoms that all have the same number of electrons?
No . all the atoms have same no of protones.....
Molecules And Atoms are the same thing True or False?
false
True or false atoms of different elements have the same never of protons?
All atoms of the same element are the same.7) Isotopes are a family of atoms all of which have the same number of electrons, have the same number of protons in their atomic centers, but different numbers of neutrons.
True or false a chemical is always the same thing as an element?
FALSE
Do atoms have the same propeties as their element?
Yes, it is true.
True or false the graphite in your pencil and the dimand in a dimand ring are from the same element?
True - the element is carbon
Electrons are the smallest particle of an element that retains the original characteristics of the element?
No. This is a definition of an atom. Electrons are only part of atoms.
True or false- all atoms of the same element have the same atomic number?
The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.
A given compound usually contains the same relative number of atoms of its various elements true or false?
Today this affirmation is not generally valid.
