How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
Two and two
How would you describe the nucleus of the atom?
the nucleus is the control center of the entire atom the nucleus of an atom has 3 basic subatomic particles: -the electrons which orbit the outside of the nucleus, electrons have a negative charge -the protons which are inside the nucleus and have a positive charge -neutrons which are also inside the nucleus have a neutral charge because they are neither positive nor are they negative something you need to know about protons and neutrons: the mass of the atom equals the protons plus neutrons and the atomic number of an atom tells how many protons are in an atom really being in the nucleus. The nucleus of an atom can best be described as the part of the atom with the biggest mass. It contains an atom's protons and neutrons.
How many protons and how many neutrons in the nucleus of a helium 4 atom?
2 protons and 2 neutron
The nucleus of a helium atom contains four subatomic particles how many neutrons does the helium atom have?
Helium has two neutrons and two protons in its nucleus.

What are the two particles called in the centre of an atom?
Nucleus (and it consists of protons and neutrons).
Describe the nucleus of an atom?
The nucleus is an organelle, enclosed within the cell that stores the cell's DNA (genes and chromosomes) and coordinates the cell's activities. The nucleus is the control center for the cell.
What are the locations of the subatomic particles in an atom?
Neutrons and protons are bound together in the nucleus at the center of the atom; electrons occupy various orbitals or energy levels outside and around the nucleus. Neutrons are neutral or have no charge, protons have a positive charge; electrons a negative charge.
Every atom is made up of how many parts?
Every atom consists of sub-atomic particles called which neutrons, protons and electrons. Electrons revolve around the nucleus and protons and neutrons stay inside the nucleus.
