Why at atomic number not whole number in most case?
The question is based on an ignorance of what an atomic number is. It represents the number of protons in an atom of the element and is always, ALWAYS a whole number.
How can you sort the parts of an atom by their charges?
You can sort the parts of an atom by their charges by considering the number of protons and electrons they contain. Protons have a positive charge, electrons have a negative charge, and neutrons are neutral. The atom as a whole is neutral, meaning it has the same number of protons (positive charge) and electrons (negative charge).
Why are atomic numbers always whole numbers?
Atomic numbers represent the number of protons in an atom's nucleus, which are always whole numbers because protons are indivisible particles. Atomic numbers cannot be fractions or decimal numbers because they refer to a count of discrete, whole particles.
Is an electrically neutral atom the number of protons equals the number?
Yes, an electrically neutral atom has the same number of protons and electrons. Protons have a positive charge, while electrons have a negative charge. When these charges are balanced, the atom as a whole is neutral.
Does a neutral atom have the same protons and electrons?
Not necessarily. The number of protons must always equal the number of electrons in a neutral atom, but the neutron number can vary, depending on the isotope of the element in question. This is because the neutron carries zero charge, so it des not matter if there is a different number of neutrons.
Why are atomic numbers listed as whole numbers?
The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.
How do the charges of protons and electrons compare in an atom?
We have 2 kinds of ions: anions and cations. Anions have an overall negative charge. This means that there are more electrons than protons. ( Electrons have a negative charge) Cations are positively charged. They have more protons than electrons. (Protons have a positive charge)
Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
How do you get the number of protons electrons and neutrons from the atomic mass number and atomic number?
Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge
Explain how the atom is neutral as a whole?
Atoms are made of protons, neutrons and electrons. Protons are positively charged, electrons negatively charged and neutrons have no charge. Since the number of protons is equal to the number of electrons in any given atom, the overall charge of the atom is neutral (negative charge of one electron cancels the positive charge of one proton) Atoms that are positively charged (cations) have lost one or more electron(s). Atoms that are negatively charged (anions) have gained one or more electrons.
Why is it the whole atom has no charge?
Because unlike charges attract, like charges repel. When atoms have a charge they are referred to as 'ions'. If the atom has the same number of protons and electrons, it will have no charge because the positive protons and negative electrons cancel each other out. If the atom's protons and electrons are unequal in number, the atom is referred to as either a 'positive ion' or a 'negative ion', as applicable.
What kind of charge does the a whole atom have?
Every proton in an atom's nucleus gives it a positive charge equal to the negative charge from the electrons orbiting the nucleus. The charge of the entire atom is neutral if there are an equal number of protons and electrons. If there are an unequal number of protons and electrons, the net charge of the atom, which is now an ion, is plus or minus e for each extra or missing electron. For example if an atom has 6 protons and 4 electrons, it has a charge of plus 2e.
