What atom of an element with a different number of neutrons?
Isotopes.
What is the chemical symbol for an element whose atoms have 11 electrons?
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
What is the number of electron whose mass number is 75 and whose number of neutrons is 42?
The mass number is the sum of protons and neutrons in an atom. If the mass number is 75 and the number of neutrons is 42, then the number of protons would be 75 - 42 = 33. Since atoms are electrically neutral, the number of electrons in the atom would also be 33.
Element whose neutral atoms have 12 electrons?
Atoms of Magnesium have 12 electrons. Elements in the periodic table with a neutral charge must all have a number of electrons equal to the number of protons in the nucleus. Since Magnesium has an atomic number of 12, and the atomic number is also known as the PROTON number, then it must also have 12 electrons to balance out the charge. Magnesium has an atomic mass of about 24 - the other 12 units of mass being made up of neutrons.
What is an isotone?
An isotone is a group of atomic nuclei that have the same neutron number but different atomic numbers. This means isotones have the same number of neutrons but different numbers of protons. Isotones are different from isotopes, which have the same atomic number but different numbers of neutrons.
What is an element whose atoms have a different number of the neutrons?
isotope
Element whose neutral atoms have twenty protons?
''CA" (CAlCiUM)
Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
What is the atomic mass of an element whose atoms consist of eight protons nine neutrons and eight electrons is?
The Atomic Mass is 17
What is the element whose atom has 8 electrons when neutral?
The number of electrons corresponds to the "index" number of the element in the periodic table. The 8th element is Oxygen, which has 8 atoms when neutral. That didnt answer the question. ANSWER Neon has 8 electrons :)
What atom of an element with a different number of neutrons?
Isotopes.
What is the chemical symbol for an element whose atoms have 11 electrons?
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
What is The atomic mass of an element whose atoms consist of seven protons eight neutrons and seven electrons?
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
Isotopes are atoms whose nuclei have the same atomic number bith with different number of?
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons in their nuclei. This results in isotopes having the same chemical properties but different atomic masses.
A substance whose atoms all contain the same number of protons and the same number of electrons are?
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
How many electrons are in an oxygen atom that hasan atomic number of 8?
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
What is the number of electron whose mass number is 75 and whose number of neutrons is 42?
The mass number is the sum of protons and neutrons in an atom. If the mass number is 75 and the number of neutrons is 42, then the number of protons would be 75 - 42 = 33. Since atoms are electrically neutral, the number of electrons in the atom would also be 33.
