What else can I help you with?
An example of an atom that has no charge is one that has A 2 protons 2 electrons and 1 neutron B 1 proton 2 electrons and 3 neutrons C 3 protons 1 electron and 3 neutrons?
The atom that has no charge is option A: 2 protons, 2 electrons, and 1 neutron. This is because the number of protons (positively charged) is equal to the number of electrons (negatively charged), making the atom electrically neutral.
What element has only 1 neutron?
The isotope helium-3 has only one neutron. It has 1 neutron, 2 protons and 2 electrons. You can get an atom's number of neutrons by subtracting its atomic number from its mass (nucleon) number.
What element has 5 neutrons 4 protons?
Beryllium
What is tha neutron for calicum?
An atom contains protons, neutrons, and electrons. The electrons are tiny. They can be found in a fast-moving cloud, orbiting the nucleus. Each electron has a charge of -1. The nucleus contains the protons and neutrons, which are packed tightly together. The protons each have a charge of +1, and the neutrons have a charge of zero. The mass number of an element is the number of protons and the number of neutrons added together. Since the number of protons is equal to the atomic number of the element, the number of neutrons can be found by subtracting the atomic number from the mass number.
Which two subatomic particles are present in equal numbers in an atom?
In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.
How many protons neutrons and electrons are there in 3He?
3He has 2 protons, 1 neutron, and 2 electrons.

How many electrons neutrons protons are in hydrogen?
1 proton,1electron and no neutron
Is it true that Unlike protons or neutrons electrons have no mass?
no electrons have mass, about 1/1800 that of a proton or neutron.

How many protons and neutrons and electrons does helium-have?
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons

What element has 1 protons 1 neutrons and 2 electrons?
It is hydrogen element. It is tritium isotope of hydrogen.
How many protons neutrons and electrons in H1?
There are 1 proton, 0 neutron and 1 electron in H1.
What is helium gas mean?
Helium is a gaseous element at STP and has 2 protons, 2 electrons. He-3 isotope has 1 neutron whereas He-4 isotope has 2 neutrons.
